Default Impact of +1 Wheels on Ride Quality

Trying to decide which way to go with wheels. As you know, many of the nice looking, quality wheels are not available in 17/18. If I go to 18/19, I want to keep the wheel diameters close to stock to avoid speedomenter error. Therefore, the tires will be lower profile. If I fit non-run flats of the appropriate size on 18/19 wheels, how harsh will that make the ride?

Many thanks,

Joe

The dam run flats are worse riding in the problem here that you are talking about. The only problem you really need to look out for is hitting a big hole in the road. Robert

When I went from the stock rims 17"/18" run-flats to rims 18"/19" regular tires, it was an improvement. In-other-words, it was less harsh on bigger rims.

I should say that I'm on the Michelin ZP AS plus tires right now, so as I understand it I'm already enjoying a ride improvement over the OEM Goodyears. Thus I had more concern about erosion of ride quality in going to bigger wheels.

I've run 19/19 and 19/20 on my C5s and really didn't notice any decrease in ride quality. A good set of tires helps, especially if you go with non-runflats which offer more flexibility in the ride.

Haha I just switched to +1 wheels and mounted these tires on them. It now rides like a Cadillac (for good and bad). I ended up setting my shocks to the stiffness recommended for the track and it's still super plush. Kinda funny. If I didn't have track wheels with real performance tires I would probably be a bit disappointed. Now it's just nice not to feel the terrible roads as much.

Are all you folks with the good experiences keeping your tire diameter stock with lower profiles?

19s all around here. Ride quality is fine.

If I was worried about that I wouldn't buy a sports car.

I'm running the same 19/19 as above.

My ride quality improved compared to my stock sized Z06 GY SuperCar tires. I thought it would get rough with the 19/19, but it was just the opposite !

I'm running 19/20's on mine with coil overs. The ride isn't as great as stock, but I only put about 1,000 miles on it a year.

A lot of it will depend on the quality of the roads you'll be primarily travelling on.
