Can You Use Larger Pilot Hole Diameter on 15 Inch Trailer Wheel w/ 6 on 5-1/2 Bolt Pattern

Question

Question:

I have an 1976 Airstream Land Yacht. My 15 rims have a 3.65 pilot diameter with .625 valve stem hole. My 2020 GMC 2500 trailer TPMS are to small. Can i use a tire rim with a 4.27 or 4.29 pilot diameter. I have seen them with a 0.453 valve stem that would work. The rim I need needs to be 15 -5.5 6 lugs

Yes, you can switch from to a 15 inch wheel with a larger pilot hole diameter than what you currently have, so long as you go with a lug-centric wheel. Those are the most common (by far) and that just means the wheel centers and mounts to your hub's lugs as opposed to the hub bore.

So you can go with any of the following, which all have a 4.27" pilot hole diameter and 0.453" valve stem hole diameter:

- Dexstar Steel Spoke Trailer Wheel - 15" x 6" Rim - 6 on 5-1/2 - White Powder Coat # AM20532

- Dexstar Steel Mini Mod Trailer Wheel - 15" x 6" Rim - 6 on 5-1/2 - Silver Powder Coat # AM20539

- Dexstar Steel Spoke Trailer Wheel - 15" x 6" Rim - 6 on 5-1/2 - Silver Powder Coat # AM20535

Yes, you can switch from 205/75-14 tires to 225/75-15 tires if you have the clearance all around the existing tires. You will also need to replace the wheels though because a 15 inch tire will not fit on a 14 inch wheel. I recommend going with radial…

For a wheel that is 5 inches in width and 15 inches in diameter you would want tires that are size ST205/75-15. For the tire size ST225/75R15 you listed you would want a rim that is from 6-7 inches in width. I attached a department page that has all…

The importance of matching a wheel's pilot hole diameter to the part of the hub that fits through it depends on the type of wheel. A hub-centric wheel uses the pilot hole to center the wheel on the hub and also to bear some of the total weight…

Hi Hayden; that bolt pattern is really uncommon but I believe it can be found on some really old Airstream trailers. There are no modern replacements that will match. The best option is to replace the hub with one that has a common bolt pattern like…

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…
