So the new season is fixing to start and the biggest rule change is that now the tread wear is 200 instead of 140 where it used to be. Whattiresare going to be best in the lineup now in that tread category?
Maybe, alot comes down to sizing. For a H-Street SVT or a STF SVT on 17" wheels, the Z2 Star Spec in 215/40/17 is probably the PERFECT tire. It's one of the fastest tires and nobody else makes a fast 200TW tire in that size.Ok so your saying that the options out there now arent worth buying until the new models that are being made are come out?
Pretty sure the 215/40/16 doesn't exist.Im running h street right now in my svt but im running 16 inch tires since they were an easier and cost less to aquire the rim. But may eventually bump up to stf. So im looking for a 215 40 16 to be exact. But I assumed that the tire recommendations wouldnt really go by sizes too much. Any idea of when the new rubbers are coming out or should I really consider the z2 as a top choice no matter what?
In street, tire width is unlimited, wheel width is limited to stock width. Wheel diameter is stock +/- 1"I was aware of the rim size rules, has to be stock width but can go up or down a inch in diameter. However I was just reading through the rules and I could not find where it says that Larger then stock width tires are allowed. Im all for having a bigger tire so if this is true then I would love to take advantage of it but id hate to buy a tire that I couldnt use though.
I'd disagree, but testing is truly the only way to prove this to yourself. I did this a few years back on my 240sx. I was running 245's on an 8" wheel. Steering what numb and felt floppy, car was quick but not fast. I put those same 245's on a 9" wheel and they came alive!However, the 225 on the 7 in rim is a good fit.
From the same threadAndy Hollis said:We found that a 205 Rival on an 8 turned the same lap times as a 225 on an 8, but they did it a bit differently and the feel was different. Only when the 225 went onto a 9 did it pick up time. As a further data point, the AD08R in 205 on 8 was faster than the Rival 205 on 8, but not quite as fast as the 225 Rival on 9.
That said, your car isn't going to spontaneously explode by putting a 225 on a 7" wheelWhy on Earth would you do that? A 205 would have been a lot better.That could account for why I didn't like the feel of the Rivals vs ZIIs. I was running a 225 on a 7" wheel.
So many years of people successfully cramming Hoosiers onto miniature rims has corrupted the thinking of autocrossers everywhere.
If it were me, at this moment, I'd go with the 215/40/17 Z2 Star Spec.Ok now you guys are making things more difficult lol I understand what your saying about the widths and since this isnt drag racing that biggest isnt always better. That being said I dont want to buy the bigger tire if it is known to be slower since this will strictly be a race tire and will never see the street, is there not more info on tires and sizes that seem to be winning in street and stf?
