Forum,

I've currently got a 10.5" square set up on my RWD with 255/35/20 all around.

The rears are almost bald and I'm planning to replace them with either of the following sizes:

- 255/35/20
or
- 275/30/20.

Question is should I be staggered since the car is RWD? Or get the same size for all corners?


Thanks in advance

There is a handling benefit for staggered but you'll not suffer much in that regard staying square.

 

Will it alter in the speedometer reading?

 

More input will be appreciated people

 

Use the tire calculator on this site to find that answer. Or, some simple math in a spreadsheet...

 

you'll get more understeer switch to a staggered setup and wont be able to rotate your tires so if your like me you'll have replace two sets of rears for every front (potenza s04s are amazing but dont last long im switching to 245/40-19 and 255/40-19 so it has less understeer but since I have as grippy tires idk if I want the exta oversteer from the staggered, handling will be more neutral the less stagger there is.

 

This is the best for comparing multiple sizes Tire Size Calculator - Tire & Wheel Plus Sizing

and this is comparing visual size and percentage change so you can keep your vdc happy.

I'd stick w/ square, and run a small spacer if you want more flush in the back, like mentioned, being able to do a true 4 wheel rotation is a good plan.
BTW are your tires wearing evenly?

 

Running staggered allows a bit stiffer rear stabilizer. Or, it helps tame too much oversteer.

 

255/275 combo fine as well as 255/255. The wider tire out back will help plant the rear end in corners better, the 255s all around better wet traction with the narrower footprint. You'll lose the ability to rotate them if stagg as well. Majority of people run 255/275 for handling and looks. If that's not your goal, and you like the way its set up now, keep it square.

 

Went with 255 35 front 275 30 rear. Thanks for all the input!
