Goal: Run 275/70/17 K02's without rubbing and without cutting the body.

I'm very new to the world of 4Runners and recently picked up a Gen5 SR5. I definitely want to put a more aggressive tire on there and really like the K02's. However, I also figure I might as well step it up a size or two in the process.

Can I run 275's on stock suspension? Do I need a lift? Is it possible to run 285's without cutting the body with a lift?

I really want to avoid any body chopping if at all possible. Any info is appreciated as well as pictures of anyone's ride that matches these specification. Thanks!

 

With the right alignment (caster pushed up to roughly 4*) and the proper wheel offset and backspacing (stock wheel specs), you should have no problem running 275’s without trimming.

In addition to using the same parameters above, with 285’s you will probably have to push the front fender liner forward an inch or so and do some very minor trimming on the front bumper lip, but it’s very minor stuff, not noticeable from an aesthetic standpoint, and extremely easy.

A lift is not necessary with 275’s. Some people have gotten away with running 285’s without a lift, but a small lift in the front (1.5” or so) is probably best to help clear your up travel.

I have 285s and a 1.6” lift in front. I did some minor fender trimming ahead of even seeing if there was any rubbing or not because it was such an easy job that doesn’t affect looks whatsoever. I have stock trail wheels and zero rubbing issues.

I don’t have access to any pics at the moment, but I did post one over in the “what have you done to your 5th gen today” thread a week ago.

 

This is all great info I really appreciate it! I'm new to all the jargon such as "caster, wheel offset and backspacing" in terms of what they mean and how they effect the overall probability of tires rubbing. Looks like I need to do some major homework.

 

This is really helpful as well. 3rd box from the very bottom gives you stock wheel backspacing numbers in case to decide to go with aftermarket wheels and want to get some that won’t cause your tires to rub. There are also threads you can search for that explain optimal alignment setting with bigger tires. It will help you understand caster better.

Here’s a pic of my set-up with 285s
