I'm going to be picking up my first Elise this week that has black CE28's wearing Toyo Proxes RA1's in sizes 225/45/15 and 245/45/16. I am told they are about 50% worn. Are these pure track tires? Am I going to be ok driving these around on the street until they wear out? What about in the (florida) rain? I did a check on Tirerack and discount tire and there aren't many options in these sizes. When they wear out do you think it would be better to go with a less meaty tire? Will a 225 in the front make turning more difficult?
