I went with the 305/35-18. I'd rather have a 315 size but never could really find one. As much as I'd like to have the 335, I just can't see those ever fitting. Oh and VWW wheels only come in widths up to 11". As much as I'd love to have some Formula 43 Laguna Gray Profile 5s they just weren't in the budget at the moment. Maybe some day...
I also wanted to go with the R888. I ended up the Nitto 555R. Reasons being:
1. Not sure when i'll get the car on the road so the less I spend on tires the better since they might dry rot
2. Not convinced I would like this size so spending less makes changing later easier
3. Discount Tire was running a Labor Day sale with 100$ rebate on set of 4. That and their free shipping ended up making this 555/555R combo $400 or so cheaper.
