Tire Sizing Help - 5th Gen Toyota 4Runner Trail Wheels

[KauaiTaco]

Hey guys so I have a set of Toyota 4Runner trail rims on my tacoma currently right now and also have a westcott 2.5 Level/lift, I wanted to run 285/75R17 but some say that it'll cause rubbing and I don't really feel like cutting up a brand new truck, just wondering if anyone has any similar setups on their taco, I believe the offset on my rims are +15 other than that they are 17x7.5 ill include a picture. any help appreciated.

You might have some minor rubbing. But a positive offset with a 34" tire is on the less likely side to need any bigger cutting/trimming. Are you planning on off-roading at all or just driving on the street? Things usually rub a lot worse off-road.

I would say my off-roading level is a medium, I don’t do it everyday but I like go out once in awhile, if it’s a huge problem, should I wait to upgrade to a 3.5 kit then just throw 35’s

The lift kit will help, but mainly on road. When the suspension flexes to full compression, especially at full lock, the lift kit is irrelevant. That's why true tire fitment only happens when they don't rub in the extremes. Sure, on the road you will move the truck farther away from the tire. But that gain goes away while flexing off-road. That's why I ask. If you're mainly on the road and on light duty trails, you won't have as many potential issues as while off-roading.

But with a 34" tire, which is only about 11.5" thick, on a positive offset 7.5" wide wheel, you should be pretty clear. But there's nuance with every wheel and tire setup. Tough to give a one size fits all answer.

Sounds good, thanks for the help hopefully when I finally have enough money to buy new rubber, I can post a picture here haha. I appreciate the clear and concise explanation. 34’s with the 2.5 level seem like a good idea to try
