No 225 45 15.... </3

True that there's no 245/40 15 but based on TireRack the Dunlop ZII* 225/45R16 has a 8.5" thread width which is the same 8.5" thread width as the BFG 225/40R15. If the ZIII follows the same ZII* sizing they should be the same 8.5" wide but with a smaller impact on gearing than the BFG 225/40R15 tire (23.9" vs 22.7"). Maybe not a big deal for everyone but it's about 3 mph difference before hitting the rev limiter in second gear which can be important in AutoX.
I just wish we had some info on how sticky they are compared to RE-71R and the Rival S 1.5...Comment

Seeing as how the RE-71's are backordered this time of year I'm interested in how the Z3's compare both at the autocross as well as daily driving in the rain. I'm not concerned so much with treadwear as I am driving on the highway through the rain after a long day at work. The new Continental ECS are also on my radar, all sizes 205-50-15. Treadwear isn't an issue; if these tires get me thru to the fall with autox every 2 weeks I'll be happy.

In fact, they used to the be both Spec class tires for years, we were just shaving them to slick for the dry. I haven't experienced the r1r yet, but they also look promising. Just hard to justify spending dough on tires that don't fit in any of my motorsport duties, though.Comment

Anyone done a back to back with the ZII and the ZIII?Comment

FYI- Grassroots Motorsports has a tire review this month. It’s rather in-depth and makes comparisons between Rival S 1.5,Re-71r, z3, z2 and azenis. Worth while finding a copy at a local bookstore.
Based on the what I read I’ll be sticking with Rivals S 1.5 for Autocross.Comment
