So would you think a pirella p zero tire would be good enough in 20-100 degree weather with rain? Or should I have a winter set up in which it would have to be on 20s and be 295 front and 335 rear pirelle sottozero series 2 winter tires. I would put michelin PSS but they don't come in 355. And the p zero corsa that comes with the track pack I really can't use in rain since it is almost R compound I believe like the michelin sport cup tire. So I would just get the OEM regular p zeros to put on my HREs.
Not sure how much it compares, but I know some Jags used to come with P Zero tires on them, and I don't think there were any weather concerns with those. I know the 98 XJR my parents had used them as stock equipment and they were moderately wide (285 maybe?). Not really the same class as the Viper, but you get the idea. You could probably put the old Gen 3/4 345's on the back as well without hurting anything. Wouldn't think the slight reduction in tread width would be that big a deal.
