I bought a set of AP1 rims with the idea of mounting winter tires. I didn't check as carefully as I should and ended up with 3 ea 16 x 6 1/2 and 1 ea 16 x 7 1/2. Front rims/tires OK but the rears don't match. The two questions.

1) how bad would it be to run one 16 x 6 1/2 and one 16 x 7 1/2 on the rear. The tires, Blizzak WS-60 225/50R16, have a rim requirement of 6-8". I know the answer and don't want to do it but I had to ask... (BTW, the wheels came off a car sold by a dealer ;-)

the second question might be a bit more reasonable. It might be easier to pick up another 16 x 6 1/2, so

2) would it be possible to run 16 x 6 1/2 rims all round. The tire requirements (for 225/50R16 and 205/55R16) are 6-8" and 5.5-7.5" rims so 6 1/2 should work. The 16 x 6 1/2 have offset of +55 so the +43 and +53 requirements are OK?

A 'cheap' OEM 16 x 7 1/2 for sale in OKC, Tulsa, North Dallas or even Denver would be the best answer...

Thanks

 

H'mm 'AP1 wheels weighed 15.5 lb. and 16.5 lb' (from another post). Not a big difference but also 10mm (0.39 inch) offset difference...

Or 17.5 and 18.6 lb on http://wheelweights.net/ (Cast)

 

who sold them to you? i wouldn't run that size because the different weight might cause harm to the differential. someone correct me if im wrong

 

Private sale, taken off a car bought second hand from a dealer... yeah, I'm not excited about trying the mismatch... (hadn't thought about diff problems) and I was all set to have the tires mounted tomorrow... I guess I'll wait awhile and try and find one more AP1 rim ;-( At least the weather is warm this half of the week :-) in OK that will change.

 

Weight isn't the issue, but the overall rolling diameter of the mounted tires will be slightly different between the 6.5" wheel and the 7.5" wheel, even if the nominal tires size is the same. This difference will put a constant torque on the differential. Bad idea.

 

You could still run the staggerd tires but the big problem would be a vibration with the front wheel run on the rear. Your front wheels have a larger center hub so the wheel will not be hub centric.

Why go through the hassle of using the front rim and then getting hub rings? Wouldnt it be easier to just buy one more ap1 rear? ap1 rims are cheap and easy to come by.

 

here you go!!reconditioned OEM's for $162

 

I thought it might be quicker (and a little cheaper) to include a front rim in my search since I had one 'extra' of each front and back.
