Seems odd the dealer would put a 12.5” wide tire on a 7.5” wide wheel?
You seem to be implying that the average dealerships interests extend beyond the sale of a vehicle.
I would think so, but I know some people do. I would think it would affect the lateral stabilization of it.
You would think, from a liability standpoint, they would put a tire size in spec with the wheel. What i will say is , i looked at this wheel really close, and it did not appear to be crowning or have side bulge, indicating at least an 8.5” wide wheel. But I can’t find any on the mopar site that matches up?
Correct. While tire manufacturers do not recommend mounting a 12.5-inch wide tire on a wheel less than 8.5 inches wide, some tire retailers will still do it.
They are 7.5 wide. I ran a 315x75r17 on the stock rubi wheels and know others who run 37x12.50 on them as well. Usually have to run lower pressure then recommended especially on an E range tire. Some see uneven wear while some are fine. Even knew a guy who kept his off roading tires on stock wheels because he was convinced, that at low pressure, the tires stayed on the narrower wheels more reliably..... I'm not advocating doing this but I was unable to find any info about a tire coming off the wheel or causing a dangerous situation. Just the possibility or likelihood of uneven wear.
That's a 7.5"wheel
Milestar approved rim width for 37/1250R17 Patagonia #22050500 is 8.5-11.00 according to their site, which is consistent with all manufacturers in that size.
