Hi guys so I bought Staggered rims for my Lowered G35x and I need to if anyone knows the tires I need to keep them within 3% rolling diameter of eachother since my car is awd. Please help thank you. I'm lowered on Tein Springs if that helps too. im worried it hit the fender if i buy the wrong tires

p
the specs : front 20x9 +35 Rear 20x10.5 +40

 

You need to see how much clearance you have for tyre choice. Also try a tyre size calc.

The 3% rule is for RWD cars to keep the traction control happy. For an AWD car you need the tire sizes to be pretty much spot on the same size or it'll prematurely wear out drive-line components and tyres.

If you're set on running staggered wheels you'd be looking at something like 235 35 with 275 30 or 245 35 with 285 30 to keep the diameter as close to matching. Your tyre choices will be limited by the AWD requirements.

Both tyre size combinations I suggested would have a 0.4mm diameter difference, that is acceptable to run on an AWD car.

 

Agree with above.

3% rule is usually for ABS and traction control systems. Anything greater tends to throw them for a loop. With AWD, you really need it closer. 1% or less.
