QuestionBarry,
I have a 97 Suburban K1500 4x4. I'm looking to upgrade the rims and tires. I believe it currently has 16x8 stock rims and the tires are 245-75R-16 load E 10 ply tires with 3 different brand tires on it.I bought it used privately and want all matching tires of course.
I'm looking to put American Racing AR-23 rims staying at 16x8 but putting on BF Goodrich TAs 295-75R-16.Will the tires fit or should i go to a smaller width? I want to go as wide as the rim will allow. Isnt wider better or is there any downsides i should worry about? I'm positive theres plenty of room in the wheelwells and there shouldnt be any rubbing i hope.
Also should i stay with an E load 10 ply tire or just go to a D load 8 ply tire. What is the difference?I dont use the truck for towing if that would be a factor?
Thankyou,
Andrew
AnswerAndrew,
First I think you need to look at your vehicle placard for the original tire size. I think you'll find it was P245/75R16 - so the LT245/75R16 is already an upgrade.
BTW the original rims on the vehicle were 16X6.5.
I can't tell you what will fit in the fenderwell as there isn't a book that lists this type of stuff.
But the down sides to going the direction you're going is that you are raising the center of gravity on an SUV, and while this particular SUV is not noted for its rollover tendancy, SUV's are generally more suspectible to rollover.
Also, wider is the wrong direction for snow traction, hydroplaning resistance, and fuel economy.
The difference between a Load Range D and a Load Range E (assuming the same tire size) is that the Load Range E can carry more load by allowing more inflation pressure. This means a slightly stronger casing. Many people think that the stronger casing is better even if you don't need it, but I think the differences are exaggerated. Nevertheless, if you need the higher load capacity you should use the Load Range E.
And - NO!!! - An LT295/75R16 will not fit on the stock rims. They require a minimum of 7 1/2".
