Biggest Tires on Stock 215/70/15

Hi Everyone,

Completely new to this forum (and tire upgrades in general), so big thanks to everyone ahead of time.

I have a plain 2009 Access Cab, 4x2 SR5 (no Pre-Runner or TRD upgrade). My stock tires are 215/70/15. I'd like to know what the biggest tires are that I can upgrade to while retaining the stock 15 inch rims -- without having to perform any lifts or modifications. It goes without saying that I'd like to not have any rubbing or any other problems (i.e. brakes, etc.) arise after the change.

I've read that +3% is the most I should go in terms of total diameter increase, but I've also seen others here upgrade to 225/75/15 (+5.4%) and even 235/75/15 (+7.6%). Will these work out, or am I limited to 215/75/15 (+3.2%)? I'd prefer to go bigger if possible.

Thanks again for any feedback!

 

Any thoughts? Hoping to get some new tires within the next couple of days.

Thanks!

Thanks for the quick responses.

I'm assuming this means that 225/75/15's and 235/75/15's would be issue-free without any lifts/modifications? I'm not looking to go beyond 235/75/15's.
