Problem is, with the loss of the R888 275/40R18 tire, nothing really exists any more to properly fit a set of TD1.3 18 inch setups. 235/40R18 at 25.5 OD and 275/40R18 at 26.7 gave our cars a perfect rake. We are now stuck with the 275/35R18 with an OD of 25.6. I ran these before the 40 series became available. I instantly like the 275/40R18 better. The offset makes finding a set of wheels for this vehicle very challenging. I know my OD's , widths etc quite well, but wheel offsets are a different story.
ET 52 (18's) ET55 (19's) and ET 69 roughly for the 19/20 combo are real tough ones. Expensive enough using stock wheels although used cast sets with a few dings are not so bad, but going custom quickly gets you over $2000 at a minimum. Maybe folks that have found solutions can add to our list of choices. Hopefully I will get lucky and Tire Rack has 275/40R18's in stock one more time.
Forget street tires. I'd love to know what folks run at the track. Michelin Cup @?? Toyo R888, 888r?? Hoosiers.... Nitto supposedly makes a size for us but haven'yt tried them. I want to stay at least with the R888,R888r level of grip I am used to. Currently I run Toyo R888r front in size 235/40R18, Rear Toyo R888 in size 275/40R18. The R888's have been discontinued but I have been able to source them thus far.
If forced to lose an inch of OD going to a 275/35R18 at 25.5 instead of 26.5-26.7, what would be the best fronts to run to maintain the stagger and rake???
