Does anyone know if it is better to mount your rain tires on heavier wheels? When I bought my car the rain tires were mounted on oem wheels.

i too have my rains mounted on oem wheels that are quite heavy.all i know is that the wheel weight slows down the steering reaction.dont know if it is better or worse.i ran my first race a few weeks ago in the rain at msr-h and have nothing to compare to

Rain or dry, rotational mass is your enemy. And the issue will only be magnified in bad traction.

I think most would mount rains on OEM rims since they may be able to stand up to more abuse that may come from an off in the rain.

Have a great day,

I agree with Tom. I can't imagine a circumstance where more unsprung weight HELPS you.

I've found the most important changes to make for rain (and I'm talking sloppy track) are to disconnect the sway bars and adjust tire pressures according to track conditions.

I prefer to disconnect BOTH swaybars, but many prefer to just disconnect the rear bar.

I've found much lower pressures are best for a wet track where standing water isn't an issue and much higher pressures where hydroplaning avoidance is the primary concern.

Cheers,

Dean

The weights that I've seen for the OEM 15x6 wheels is 13.1 lbs. Which wheels are you using and what did they weigh?

Agreed, but never never run in hail. It's tricky stuff, very sticky one lap and slick as snot the next. You might find yourself replacing one whole side of your car [Frown]

The previous owners probably just figured they don't use their wets very often and aren't as concerned about optimal performance when they do so they just mounted them on whatever they had on hand rather than buy another set of wheels.

Slim Jim;
i smell an insult there ... somewhere ... [Cool]
if it rains today, the only thing i'm getting wet is my hand going into the cooler to grab a beer ... i'm done for the day.
now, back in the day (2004-2006)when i was a legend in my own mind, rain meant ... Victory!
go ask Carbonell- Buras - Van Vurst - von C ...
all the wet races i ran (8 in total) against those lite weights = P-1 ... so there ...
