Yah, I know. Another tire thread. But I really don't know much about tire sizing and tire rack has been absolutely no help at all. 2005 Elise with LSS wheels currently running Advans 048s. I have over 10,000 miles on them with 4 track days and in absolute need of new rubber. Currently have 195-50R16s 84W LTS Advan 048s on the front and 255-45R 17 90W LTS Advan 048s on the rear. I would like to change to R888s all the way around BUT Tire Rack says they don't have them in those sizes and cant recommend what size R888s to go to. Can anybody help me out on this? I like the current size bias between front and back and just don't know what size to go with on the R888s. I am in dire need of new tires and just don't know what to order. If it matters I am also running Nitron Singles all the way around and have upgraded sway bars and suspension. Thanks for any help!
