Daughter's 53 is almost finished. Last big thing is rims and tires. She want's to keep the rims as stock looking as possible but wider than stock. They are 5x4.5" bolt pattern. 15" or 16". The size rims that are on it stick out past the top of the fenderwell. I'd appreciate some advice as my knowledge of wheels is almost not existent. Thanks.
US Wheels can give you a couple of choices. Since your working with technically a Ford wheel pattern they sell both a “smoothie” for a inner baby moon type hub cap OR a stock appearing replacement outer and center that has the 4 original style vents or slots and accepts the 10-1/4” poverty caps of the mid 50’s up thru the 60’s for sure. The 15x6 has a 3-3/4” back space. Check what you have now by taking one off and measuring. The rim can easily take a 235-75- 15 which will look in you rear wheel well. Possibly combine with 215 for the front. They also have 5” and 7” wide. I bought my last set thru Summit Racing. Steel US Wheels are assembled in Huntington Beach Ca. and the outer rim and center stamping for these are made in the USA if that means any thing for you. I’ve been in there plant here.
Being 5 x 4.5" bolt pattern (Ford) there will be a lot of choice. Just a matter of working out what offset/backspace you need. What size wheels and tires are on it in the pic, and what backspacing are the current wheels?
Measure what you have. www.youtube.com/watch?v=BrkJM-azfUw Diameter is going to be in the side of the tire. Either 15 or 16 you said. Easier than measuring. Width is going to be a bit harder with the tire on the wheel. Try to guess as best as you can. Tire stores have a big set of calipers to do this with the tire on. Backspace and offset you want to be different, since they are currently sticking out. They look like reverse wheels which you will probably want to change to a zero offset. You can measure how much it is now and how much you want it tucked in. Measure the amount they stick out before removing them. Include any inner lip if the suspension allows the tire to tuck up into the fenders. Bolt pattern or Pitch Circle Diameter (PCD) is going to be a Ford Mopar 5x4.5. Since this is a GMC truck with a Ford pattern, things have changed. One more measurement you should check is the inner diameter of the wheel and the register where it sits. Almost all aftermarket wheels will have a larger inner diameter to avoid not fitting here. This will make the wheels 'lug centric'. Stock stuff of the right size fits tight on this inner register and is called 'hub centric'. If this is important to you, get this measurement. There are rings to adapt a bigger wheel center to the hub. It's an added expense.
Thanks for the advice everyone. I'm away from home until Thursday and will take measurements then. Appreciate it.
Ok I googled how to measure bolt pattern and I was doing it wrong. They are 5 x 4.75. The rims on it now have 2.75" from back of bolt holes to edge of rim. Front of bolt holes to edge of rim is 5". Rims have 215-65 R15's now. Front I'd like to have set 2" further inside the wheel well. For the rear I'd like them to set 2.5" further in.
Chevy 5 bolt, also common. 2.75 + 5 sounds like they are probably 15x8. Figure a normal RWD offset is zero, that would mean 4 and 4. minus the rim thickness. Sounds about right in front, maybe a bit more offset in the back.
15x7 From summit on sale for $98 ish each cam get em in chrome Cheap push thru caps with spider rings
@anthony myrick got ya! 15x7 will be more common and not be as picky about offset. https://roadkillcustoms.com/wheel-b...5-wheel-bolt-pattern-5x120.7mm-5x4.75-inches/
Doesn't look like 215's on 8" wheels in the OP's pic. I would guess those wheels are 7" wide at the most.
