What is the widest tyre size for 2007 Hyundai Santa Fe?

I am planning on getting 18" rims and would like to get wider tyres. What is the widest tyre size that can be placed on the 2007 Hyundai Santa Fe without affecting the speed or transmission.|||235 is stock so, 245 is the widest you'll want to go I think. The 1st poster is wrong, this won't damage your transmission/brakes/engine or whatever. The important thing is to make sure the overall diameter of the tire is the same as stock or it will throw off your speed and mileage readings by a couple %. check out http://www.tirerack.com As you will see, the Limited Santa Fe came with 18's, I'm not sure if you have the GLS that came with 16's, so obviously the Santa Fe can handle larger rims straight from the factory even. http://www.tirerack.com/tires/Compare1.j鈥?/a>|||well anything other than what it came with will affect the speed and transmission not the mention front end parts and alingment.. thro it might look good it does a lot of damage in the long run
