Anyone with some wise words about tires? The front tires on my 620i are getting worn down. The rear tires are still in ok shape. I have done a bit of research and learned the 25x10-12s and 25x11-12s are not too common, tho I have found some. It is probably best to go with a DOT rated tire as I have to travel on a public road to get anywhere. What problems am I likely to find if I go with a slightly different size? Some reviewers complain of rough riding due to out-of-round tires. With a top speed of 30 to 35 mph I would not expect that to be a serious problem, but... Are tubes generally required? I go on some fairly rough, rocky roads, so what ply rating is advisable?
TIA
