Looking For a Replacement 15 Tire and Wheel With 5 on 5 Bolt Pattern  

Question:

I want to order some wheels with the tires and want to make sure im getting the right ones both size and what i will need for using the trailer. Right now the now i just got has 15 in wheels and the tire size is 235/75/15. I see you only have the 205/75D/15. Will the tires and wheels you sell hold up to the same standards? The trailer will be hauling my sons car which weights around 3800 LBS. I have attached 2 pictures. Also i think i might just want to replace the hub assembles also but dont know for sure what ones i need. Anyway to tell? Also how would I know what the axles are rated for? 2000 3000? Is 5 on 5 correct wheel pattern? Thank you for your assistance

From the pictures you provided, you do indeed have a 5 on 5 bolt pattern. This isn't the most common bolt pattern though so if you were thinking about replacing the hubs as well, I do recommend swapping to the much more common 5 on 4 1/2 bolt pattern. However, due to the corrosion present in the pictures, I suggest pulling one of the hubs off to verify your bearing numbers. If the trailer is older, there can be a few different ones that were used.

If the Inner Bearing is an # L68149 (1.378" inner diameter) and the Outer Bearing is an # L44649 (1.063" inner diameter), you can switch over to the Dexter Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles - 5 on 4-1/2 # 84545UC1-EZ. This can then be mated with the Kenda Karrier ST225/75R15 Radial Trailer Tire w/ 15" White Spoke Wheel - 5 on 4-1/2 - Load Range D # AM32545 which will have a max capacity of 2,540 pounds at 65 psi and an M speed rating, or 81 miles per hour.

If you preferred to stick with the 5 on 5 bolt pattern you will need to go with the Dexstar Steel Spoke Trailer Wheel - 15" x 5" Rim - 5 on 5 # AM20428 and Provider ST225/75R15 Radial Trailer Tire - Load Range E # TR225LRE, which will get you up to 2,830 pounds at 80 psi. The Easy Grease Trailer Idler Hub Assembly for 3.5K Axles - 5 on 5 - Pre-Greased # AKIHUB-550-35-EZ-K would be the replacement hub for the 5 on 5 bolt pattern as well.

If there is no label on the axle or no rating stamped into the coupler, there really isn't a way to know 100% what the axle is rated to. But at most, I would say your axle is rated to 3,500 pounds as there are no brakes currently equipped. With that being said, I do need to mention that if your son's car weighs 3,800 pounds, it is a very good idea to add brakes if neither axle currently has any. I couldn't tell from the pictures if the rear axle has them or not, so I thought I would throw it out there. Below are the Hub/Drum options for both bolt pattern as well as brakes that will fit them.
