Will Switching From a Drop Axle to a Straight Axle Increase Tire Clearance
Products Featured in This Question
Question:
Thanks Conner for that valuable information. I have another question. Would you help me figure out why my concession trailer is 3/4” lower on one side than the other. I have ruled out the tires because they are the same height. The leave springs are not that old so I don’t think there is any sag there. What could I do to correct this? Thanks

The 175/80-13 tire that you have now is 24" diameter x 6.9" wide and the new 225/75-15 tire is 28.3" diameter x 8.9" wide. Therefore, the new tire size will be 4.3" larger in overall diameter and 2" larger in overall width. However, you will only need to account for half of each measurement so 2.15" for diameter and 1" for width.
The conversion from the 4" drop axle you have now to a straight axle is actually going to bring the spindle down in line with the axle which means you are actually going to have more tire to fender clearance with the new axle than you did with the old drop axle.
I have attached a list of our 6,000 lb trailer axles as well as our 225/75-15 wheel/tire combos for you as well. If you can tell me the spring center and hub face measurement of your axle then I would be glad to see if we have a match for you. For example, the Dexter Trailer Axle Beam with E-Z Lube Spindles part # 8327830 has a 74" spring center and 89" hub face measurement. If you were to add the Dexter Nev-R-Adjust Electric Trailer Brake Kit part # 23-458-459 with the Dexter Trailer Hub and Drum Assembly part # 8-201-9UC3-EZ you could then use Karrier ST225/75R15 Radial Tire with 15" White Spoke Wheel - 6 on 5-1/2" - Load Range E Item # AM32680, which is rated at 2,830 lbs and has an 81 mph speed rating.
