Re: R32 Wheel Crack!!! Help! (ejw1224)
I've found the stock wheels to be plenty strong (45K+, a few nasty pothoes hit occasionally on rainy nights, but still no issues http://****************.com/smile/emthup.gif ). Are you running the stock Goodyear F1s? If so they are not a good choice IMO for your area due to the very soft sidewall. If you are going to keep them make sure they are always well inflated by checking them often!
In regards to all low profile tires these are completely different from something like an SUV tire! I used to check my wife's Montero every month or so, but they held a heck of a lot of air and I could tell very easily if one was getting flat. Low profile tires don't hold a lot of air and you can't rely on a visual inspection to 'guestimate' the air pressure inside so you should be checking pressures on a weekly basis at least.
