That depends on the application. You may or may not have room for it.
To go wider you would have to go with a 265/60-17 to keep the overall diameter the same as the OEM size to keep your speedometer accurate and other parameters close to the same. Like the first answer said you may have clearance issues especially on the front. Check your clearance with the OEM tire if you have around 2" clearance you should be ok. Make sure before buy the tires. My advice is stick with the OEM size.
Doubtful, since the radial is bigger on the r17...
245/65/R17
Typically nothing, although it will fill you fenders out better. On my dodge I went from a 245/70-17 to a 265/70-17. A little taller and a little wider...
235 / 65 / R17 is ( 29 inches in diameter and the tire section width is 9.3 inches ) 245 / 70 / R18 is ( 31.5 inches in diameter and the section width is 9.6 inches )
The correct factory tire size for a 2001 Jeep Cherokee is 225/75-16.
yes, there not as wide as the 65's you have on there now-- the smaller the number, the wider the tire is
NO! This is not an acceptable swap. The 245/65-17 is 6.91% (2") larger in overall diameter. It is never acceptable to go over or under 3% of the OEM size. This will adversely effect handling, stopping, performance, and fuel mileage. However a 205/65-17 would be an acceptable swap. I would advise you to stick with the OEM size.
The 2005 Jeep Grand Cherokee Limited runs with 2 sizes available. the most common is 235/65 R17. The other available size is 245/65 R17.
