345 series tires on a Gen I

[SlayTay]

ViperClub,
Has anyone put on a set of 345 30 r18 rims and TIRES on a Gen I Viper? Its time to get some rear tires and the 17" tires are so expensive that it is almost cost effective to get some 18" rims and the cheaper 18" tires.
What brands of tires are available in the 345 size?
Do the wider tires rub anywhere?
Thanks,
Taylor

The 18 inch drag radials are 345, so the rear would work fine. I don't think I would want that size tire on the front, if that was what you are asking?

You can fit those very easy, you have 3 options for the rear.

Drag radials 345-30
Pilots 345-35 These are about 1 inch taller than 335 which makes your gearing even longer than stock.
Pilot Sport Cups 345-30 about same height as stock but will only last you 4k miles very sticky R compound tires.

In the front you can fit 295's on factory 18 inch wheels, you can put larger but then they dont look right.

They fit and look great. I have mine mounted on a set of 18'Forgeline WC3's.

I was particularly interested in the 345's for the rear.
New rims and tires are going to be my winter project, traction is gooood.
17" bald tires are baaaad...

Just a thought for you, the Purner 12.5 x 18 fronts have a greater outside offset. Anything you put on them looks more aggressive. The 3.25 x 30 tires can be driven on the street. The 3.35's can be used on the track. Either a 2.85 or 3.15 is an improvement over oem. The larger the tire goes the more darty the car will act. I have used the 3.25's on both a Gen 1 and Gen 2, there is very little difference in the fit between the two cars.
