Hello.. I am looking to get new aftermarket/custom rims for my Chevy S10. I currently just bought brand new tires, so I'm looking to get rims that will fit to them.
Tire Size: P205/75R15
I think the rims need to be 15" x 7" but I'm not 100% sure.. so that's why I'm coming to all of you for help!!!

The wider the rim - the better the handling, the narrower the rim, the better the ride. Something in between is "ideal".
There is a formula - the "ideal" rim width is 90% of the tire section width - 1".
To convert 205mm to inches, divide by 25.4 So for 205 tires - that have an 8.07" section width, subtract 1 and take 90% to the nearest 1/2"
7.07 * 90% = 6.36 - to the nearest 1/2" - makes it a 6.5" rim.
Then ... you must check each tire manufacturer's spec for the specific tire model and size.
Some tires are made to specifically optimize ride, and will fit a narrower rim, while other's will ruin the casing at the narrower size. Rims wider than the section width will also cause issues, not the least of which is that your rim will hit the curb before the tire - ouch !
While you are changing wheels, ensure that you keep the same effective backspacing as the current wheels - or you will begin to eat hub / axle bearings. As the wheel gets wider - the back spacing is less (and it can go to a "negative" backspacing) - and the opposite as they get narrower - the backspacing gets larger. The idea is to keep the center of the tire / rim in the same relative place - where the bearings were designed to take the load.
The backspacing changes by 1/2 of the change in total wheel width. If your original wheel had a backspacing of +51mm, and the wheel is 1/2" wider (13 mm), then the backspacing will change less by 7mm to 44mm.
If you are dealing with inches, same thing - 51mm = 2.00 inches. Make the rim wider by 1/2", and the backspacing is now 1.75" (1/2 of the 1/2" = 1/4").

My 98 S-10 has 15 x 7 factory wheels. Be extremely careful that you select replacement wheels with the same backspacing as the originals. If there is any doubt go to tirerack.com and call to be sure what wheels fit properly. They freely will give you that information weather you purchase there or not.
As you know the factory wheels have a very deep backspacing and if you go any wider you may risk tossing stones and mud on your truck. An inch may not bother but any more than that you could run the risk of problems . Some type of mud or stone guards may be necessary.
The bolt center is a 4 3/4 pattern. Have fun selecting wheels!
