Plus Size rims/tires

[Tusc]

The stock 275s and 335s are HUGE slabs of meat, but I was wondering if people have gone bigger?

I'm curious because I'm looking at different GTSs with factory rims and think that any potential Viper I buy will eventually get a nice set of BBS rims like the ACR - or perhaps some HREs.

Has anyone gone bigger, and what how much room is there to expand over stock? I'm not talking about 22" ghetto rims, trust me. For my purposes, the stock tire dimensions will be fine. But if I am going to buy a different set of rims, why not expand?

I have Startech 20" wheels on my 01 RT/10. 285's in front, 345's in back.

Front: 295/35-19
Rear: 345/30-19

Caution: plus rims don't work well if you've lowered your car a lot. The limit with the above combo seems to be 1" of drop; more than that, the edges will rub.

With John Purner's wheels, 18" x 12.5", you can run 335's all the way 'round on a stock Viper with no clearance problems. Stops the Viper from pushing when you're taking a corner at a high clip...

Good luck.

Those Startechs are sharp. And the Purners look good, too.

So I can fit a 335 in the front on an 18" x 12.5" rim - what is the correct backspacing for the front rims?

And am I correct in assuming then that 335 is the largest possible for the rear? I can't think of any street tires off the top of my head that are larger than 335, but is there enough clearance to accomodate a wider setup in the rear?

Thanks for taking the time to help me out with this. I don't intend to race my car, but over time I do want to be more involved with local SCCA events and club track rentals. So I don't have so much need for the extra contact surface, but I thought that if I was considering going to the expense of a new rim/tire combo I ought to go "Tim Allen" with it.

345/25ZR20's are on the rear of those StarTech's...

Yes, I noticed. +10mm is a change, but has anyone fit larger without rubbing?

Short of racing slicks, I've not hear of any tires wider that 345s. They are HUGE!

Has anyone bought the new 20" HRE's?

The 847s look great, but I haven't seen them on a Viper yet.
