Running Bigger Tires? You'll Likely Rub on Your Fender Liners & Forepart Bumper – Complete Guide to Pushing Your Liners Back & Cutting Bumper to Articulate Tires On Your 2nd Gen Tacoma

Clearing big tires can be very intimidating. At that place are a couple of different means to properly clear bigger-sized tires and some are more than daunting than others. When you leap upward to a bigger tire size, you are going to rub. Even if yous don't rub while daily driving, you may exist surprised to notice that y'all're rubbing pretty bad on sure spots once you hit the trails.

Technically speaking, a suspension lift does not e'er clear tires. This is considering the only matter that is changing is the static top of the vehicle; in other words, the tire size increases but the bike well size stays the same. Depending on the size, properly immigration tires volition require trimming to the front and rear of the inner fender plastics, the fender itself, and the firewall.

Tifanny the Tacoma

For those that don't know, Tiffany is our shop build so she goes through changes frequently.

Later on installing 33-inch Yokohama Geolander tires (285/70R17) on our 2013 Tacoma with a three″ Bilstein Lift Kit (technically 2.8″ of lift), we were amazed that the but spot the tires rubbed on was on the upper control arm. After adding a 1.25-inch spacer, the rubbing issue was solved. We were able to run 33″ tires with that 3″ lift and not rub on any of the fender plastics. This meant only 1 affair; fourth dimension to upgrade to bigger tires.

Nosotros had a gear up of 34″ tires Toyo AT2s (285/75R17) installed, and as you could imagine, the rubbing was clear. Our tires were rubbing pretty intensely on the dorsum of the fender liner well-nigh the firewall, the cab mounts, and fender flare plastics. And but slighting on the forepart fender plastics. Although the front didn't rub that bad while daily driving… if we were to stuff the tire when off-road, it would definitely rub on the front bumper fender plastics and fender flare a lot more. We decided to start clearing the bigger tires by doing a quick, piece of cake mod — the fender liner pushback.

What is a Fender Liner Pushback?

The fender liner pushback is exactly what the proper noun implies. Take the inner fender, unbolt it, push information technology farther forward, and re-bolt it to the bumper further towards the front of the truck. While this process is relatively simple, it takes some careful measuring and cutting to get it right and brand information technology look good.

Ultimately the goal is to provide more room betwixt the tire, inner fender, and forepart bumper. Yous can exercise this without cutting the front bumper, but we got a headstart on fitting 35s then nosotros cut the front bumper a piffling bit to give united states of america even more clearance.

Why Push Back the Fender Liners?

Depending on what elevator you have, and the size of your tires, you're going to rub, specially while turning to full lock. After we added a wheel spacer to clear the upper control arm, we noticed the 33s were barely scraping the back role of the inner fender. When we upgraded still again to 34s, the rubbing was worse due to the increased scrub radius.

While we weren't rubbing on the front office of the inner fender with 33s, the 34s made some solid contact while turning.

Before doing annihilation desperate similar cutting everything out or tubing the firewall, we decided to start by moving the front office of the fender liner farther abroad from the tire. While this mod only solves the issue of rubbing on the front fender and body, it'south a great place to commencement for immigration bigger tires.

We volition have multiple posts coming out on what to cut for clearing bigger tires. Check back before long for the cab mount chop, cab mount relocation, pinch weld cutting, firewall plastics, rocker console caps, and more than.

Stride 1. (Passenger'due south Side) Remove Hardware Holding Fender Liner to Bumper

Remove the 2 10mm bolts holding the inner fender to the front of the bumper as well as the clips on the side of the bumper and inner fender.

This volition allow the front of the inner fender to peel down and abroad from the bumper.

Footstep two. Move Fender Liner Out of the Way

Peel the inner fender liner completely out of the way.

We bent the inner fender liner backside the tire, allowing easy access if we wanted to test fit it.

Stride 3. Measure Cut Line

Adjacent, measure how much you desire to cutting off the bumper. We decided to cut the bottom part of the bumper by one.25″ and curve the cut line upwards until it met upwards with the factory line on the fender flare.

Keep in mind, y'all don't need to go a full 1.25″ for your cut either. Depending on your tire size, you lot may need to only cutting .5″ of material off the front end bumper. Or, yous may need to merely punch a new hole in the fender liner and button it back (steps 11 and 12). Here is an example of a really mild fender liner push back I recently did on one of my 4Runners. Check that out for another reference indicate on how to cut and trim a fender liner. Pretty easy stuff.

You can get as ambitious or as conservative every bit you want with this mod.

Step 4. Place Tape Along Entire Cut Line

Utilise tape to outline where you're going to cutting the bumper.

This will let you to cutting a shine, direct line across the whole length of the cut, all while keeping the paint on the other side of the cut prophylactic.

Step 5. Begin Cutting

Begin cutting the outer part of the bumper with some sort of cutting tool.

We used a multi-tool considering it allowed u.s. to go slow and accept total control while we were cutting upwards the stock bumper. Follow the record line equally close as y'all can, but stick to the left side of the tape in case you skid or mess upward.

Step 6. Clean Cut With Dremel

Later yous cutting the kickoff part of the bumper, take a Dremel or sandpaper (or both) and clean up the cut line.

If yous favored the left side of the tape line, clean upward whatsoever spots you missed.

Step vii. Cutting Internal Bumper Section

Next, cutting the inner portion of the bumper off.

At that place's no need to tape this part off as there is a subclass sitting in the eye of the 2 bumper plastics, merely cut the back slice and then you take more than access to inside the cycle well.

Step 8. Test Fit Inner Fender

Test fit the inner fender in its new domicile. Line up the inner fender and the bumper where yous want to drill the new hole into the fender liner.

Stride ix. Trim Inner Fender

After we test fit the inner fender, we noticed it was getting hung up on one of the pre-existing bulges in the fender plastic.

The easy fix was taking a razor blade and cutting abroad the area that was getting hung up.

Stride 10. Mark Drill Hole in Fender Liner

Next, nosotros test fit the fender once again.

Everything lined up well so we took a sharpie and marked a pigsty where we would drill through the inner fender. The marking must be done through the pigsty in the bumper since that's where the commodities is going to go through.

Pace xi. Drill New Hole in Fender Liner

Once the inner fender is marked, drill a hole through the inner fender.

Drill a airplane pilot hole first with a minor drill bit, and then employ a 1/4inch scrap to drill the terminal hole.

Step 12. Cheque Fitment of Fender Liner

One time the hole has been drilled, test fit the inner fender with the pigsty you just drilled and the hole in the bumper.

Slide the clip over the summit of the inner fender and install the bolt (or zilch tie).

Stride thirteen. Cutting Inner Part of Bumper

For aesthetic purposes, we decided to cutting the inner portion of the bumper out.

Employ a Dremel and cut as close as you can to the actual bumper. This allows for only one bumper cutting to exist shown as opposed to ii.

Stride xiv. Mount Inner Fender One Last Time

Bolt the inner fender downwards to the front bumper 1 final fourth dimension.

In one case that'south done, it's time to jump over to the driver's side.

Step xv (Driver'due south Side). Bend Inner Fender

Note:We're going to skip right to the fender liner for the driver's side. The premise for trimming the bumper is exactly the same.

Once you've removed the hardware for the inner fender on the passenger side, pull the liner out and bend it on the corner. This inner fender is a little different than the other side, so angle this at this spot allows information technology to fit a lot better in the forepart bumper, and there's no cut involved.

Pace sixteen. Mark & Drill New Hole in Fender Liner

Just like on the driver side, mark where the new hole will get in the inner fender.

Next, drill it out with a pilot hole kickoff, then a 1/4inch bit.

Step 17. Cutout 2d Part of Front Bumper

Cut out the second portion of the bumper for aesthetic purposes.

Step 18. Make clean Upwardly Your Cut Lines

Clean upwards any cut lines from the Dremel or multi-tool. Nosotros found that a razor bract left the cleanest cuts out of all the tools we used.

Slowly follow the cut line with a razor blade pealing off any access plastic from the Dremel or multi-tool.

Pace 19. Button Back and Install Inner Fender

Once everything else is done, the fender liner is ready for install.

The commuter side had significantly fewer fitment issues, and all we had to do differently was curve the tab on the corner of the inner fender outwards, rather than cut up the entire fender liner.

Final Thoughts

Overall the fender pushback was a super elementary process. You can be as bourgeois every bit yous want with the cutting or as aggressive as you lot desire. The more than aggressive you cutting, the bigger the tire you'll be able to fit, only the cutting will definitely exist noticeable. If you're looking for merely a piffling fleck of clearance, you could do this mod with minimal cutting and accept it await untouched.

Even though nosotros barely rubbed on the front with 34s (285/75R17), we wanted to make more clearance for when we get off-road and stuff the tire upwardly into the wheel well.

However much you cut/trim depends on a couple of factors, such every bit:

• How much and how hard yous wheel?
• What size tire do y'all plan on installing?
• How bad does it rub with that size of the tire?

This is the perfect modernistic for anyone who wants merely a little more clearance on the front end end of their Tacoma. Both sides took us about 30-45 minutes each and the process was very straightforward.
