Need some assistance with what size tyres to get, my 250 is rwd and would prefer to run some wider tyres on the rear. I've purchased some BBS CK's 19x8 all round. What sort of tire sizes should I go for?

 

Brilliant thank you

 

19x8 you can do 235-245 widths. You probably want 35 sidewall profile.

 

Just wondering - Why didn't you buy a staggered set of 19" wheels. Doesn't make sense to run non-staggered since your IS is RWD. The OEM wheels are staggered on RWD models for a reason - and the car was engineered with that in mind. I guess you can run non-staggered, i'm just wondering if there was a reason you chose not to?

 

The bbs didnt offer a staggered set up, the current oem are the same width alloys just running wider tyres.

Ok, another question what load rating do I need for 225/35/19 at the front and 245/35/19 at the back?
