OS-IS250

Thank you Linas, now I have a better understanding of the type of set up to go for. Appreciate you taking the time to respond to my query. Thank you again!

Purchased a set of G-Spyder alloys for my Lexus IS250. They are sized 18" 8JJ x 4. I was wondering if I can run the same size tyres all round? But not sure if RWD are supposed to have a staggered setup? If so, would the rear tyres need to be larger than the front? Need some help on this.. If someone could kindly recommend the ideal tyre size for 8JJ 18" x 4 for both front and rear. Thanks

Got a new set of 18" alloys - all 4 are 8JJ. I need a tyre set up for my RWD IS250, can anyone recommend tyre size for front and rear? Thanks

What I meant by staggered is the rear wheel size being wider to the front. I assumed all rwd cars have a staggered setup? But these came off a RWD GS300 sport and all 4 alloys are 8j's Thats why I wanted to know the ideal tyre setup for all 4x8j alloys on my RWD IS250

Images for reference..

I have a set of G-Spyder 18" alloys from a GS300 that I want to transfer to my 06 RWD IS250. All 4 alloys currently have 245/40/R18 tyres on them. I currently have the basic 17" running on Front 225/45R/17W and Rear 245/45R/17W tyres. If someone could kindly recommended RWD tyre setup for these 18" G-Spyder alloys even though this new set may not be staggered🤷🏻‍♂️ Thanks
