I've been driving 4x4 trucks for over ten years now, mainly to make my western NY winters worry free. Several times I've had a need to drive over a 4"-6" cement curb. I've done that by driving extremely slowly up to the curb, put it in 4-wheel, then crawl slowly over the curb until all four tires have passed it, then back to 2-wheel. No problems. Lately I've heard that driving over curbs is bad for tires and can damage them. However, I've read many off-road stories about climbing over rocks, which sounds as bad as the curbs. Some questions:

Assuming the stock tires are all season like the General Grabbers, is it a bad idea to drive over 4"-6" cement curbs? If not, is there a "good way" to do it? I assumed that slowly crawling over the curb in 4-wheel was the best way. Any thoughts and/or experiences?

Thanks!
