Wider tyres, More traction?

Can try but again depends on the current handling of the car and driver's preference.



Yours on 8/8.5jj rims, is it? Then use 245 all.

Racing drivers got good skill when catching the car during oversteer so they will always prefer the most responsive/neutral setup. Having use staggered for 5 years and now on square, I think I also like the square better but since I need to use 245/40/18, the sidewall height is only 9.8cm which is a bit too thin profile for my liking so slightly harsher ride than what I'd like to be. If I use staggered, I can use 225/45 at the front and 255/40 at the rear which has 3-4mm taller sidewall hence more comfortable ride. So there's a trade off between the 2 setups, whether I want more neutral handling or more comfort, that's my dilemma with my current 18' size. Probably should've gone with square 18x8.5 or 18x9 so I can just use 255/40 all around, or downsize to 17x8.5 and use 245/45/17 all around hence get the most grip with more neutral balance with still more comfort too.

Yes 8jj & 8.5jj rims. Probably need to change rims if going for square, then its gonna be 8.5jj all round.

245/45 R18 is the plan. stock was 225/45 & 255/40. Why don't you go with 245/45 R18?
