quote:You probably DO NOT want to use an increase in tire size to gain ground clearance. The first problem is that you’ll throw your speedometer, and your transmission shifts, off. You say you can live with the first, but the second may be a problem. The second is that constant scraping is usually a sign of some other problem such as misaligned exhaust parts or sagging or broken springs. The H and V rating tires will give you less wear, and are less resistant to curb and other impact damage, and you can stiffen your sidewalls by simply increasing your inflation pressure. If it were my car I’d first make sure that the exhaust system is not hanging abnormally low. I’d then measure the distance between the bottom of the rocker panel and the ground and compare it to a comparable Toyota or two to see if I have abnormally low clearance due to heavy loads, sagging springs, or replacement of the factory springs with lowering springs by a previous owner. If you find a problem, you can correct it without fooling around with the tires and wheels. Your Toyota is new enough that coil springs are readily available. If results to this point are negative, you may be able to increase ride height by going to monotube gas pressure struts (like Bilstein) or changing your coils to variable rate springs with a higher capacity than your current springs. Finally, there are both air supports and helper springs out there that can boost car clearance. Any of those approaches would be preferable to tinkering with tire and wheel assembly diameter.
Originally posted by JHZR2: I need to decide upon a new tire choice for an 01 Toyota Camry (the last bodystyle before the current one). Stock tires are 205/65R-15, the tires being used currently have s-speed ratings. What Im looking for is a tire thqat is going to be a slight bit taller, and have a bit stiffer sidewalls, thus helping to prevent scraping of the undersode of the car when going on bad bumps, ruts, etc. The car seems to scrape a LOT. I am thinking of an H or V-rated tire (tirerack has a few types that are good quality, and no more expensive than good quality lesser tires), in either 215/65R-15,225/65R-15 or something like 225/60R-15.
