The best 9R 17.5 trailer tire choice depends on the exact tire size, load rating, and wheel fitment your trailer requires. Among these options, the GREMAX 18-ply tire is best for buyers seeking a higher stated ply rating, while the Taskmaster 16-ply tire offers a 12/32-inch tread depth. The two eCustomRim listings are wheels, not tires, but may be useful when replacing a compatible 17.5-inch trailer wheel. Confirm the specifications on your trailer before ordering.

GREMAX 18-Ply 215/75R17.5 Tire

This GREMAX is an all-steel, 18-ply-rated tire in size 215/75R17.5, with load range J listed in the product details. It is designed for trailer use only. The stated maximum load is 4,805 pounds in single configuration and 5,440 pounds in dual configuration.
Best for: Trailer owners looking for an 18-ply-rated option and who need a tire for a confirmed 215/75R17.5 fitment. It was selected for its clear size, load range, and single-versus-dual load figures. Limitation: The listing is for a tire only; rims are not included. Verify the correct load configuration for your axle.
Taskmaster Advance ST215/75R17.5

The Taskmaster Advance is a radial ST215/75R17.5 trailer tire with a 16-ply rating and load range H. The product details give an 8.3-inch section width, 12/32-inch tread depth, and a maximum load of 4,805/4,540 pounds at 123 psi. It is sold as a tire only.
Best for: Buyers who want a 16-ply trailer tire and value a stated tread-depth specification for comparing options. Choose this if its load range and listed dimensions match your trailer requirements. Limitation: The listing does not include a wheel. Check the manufacturer’s load and inflation information and confirm compatibility before use.
GREMAX 18-Ply Tire Set Of Four

This listing packages four GREMAX all-steel 215/75R17.5 tires. The tires are 18-ply rated, load range J, and designed for trailer use only. The listed maximum load is 4,805 pounds per tire in single configuration and 5,440 pounds in dual configuration.
Best for: Owners replacing four tires who want the same stated tire type and size across the purchase. It was selected as the set option for buyers who need multiple tires rather than one. Limitation: Rims are not included. Confirm that all four tires match the trailer’s required size and load specification; the listed load figures depend on single or dual use.
eCustomRim 17.5×6.75 Dual Wheel

This is a trailer wheel, not a tire. Its listed configuration is 17.5×6.75, with eight lugs on a 275mm hub-piloted center and a stated 8.77-inch center bore. The description notes a +/-5.59 offset for inner or outer wheel position on an axle.
Best for: Buyers replacing a wheel who have verified this specific dual-wheel, hub-piloted fitment. It is included because wheel compatibility is essential when selecting a 17.5-inch tire-and-wheel setup. Limitation: It does not include a tire. Confirm bolt pattern, hub style, bore, and offset against the existing wheel and trailer requirements.
eCustomRim 17.5×6.75 Single Wheel

This silver trailer wheel is listed as 17.5×6.75, with eight lugs on a 6.5-inch hub and a 4.77-inch hub-piloted center bore. Its listed offset is +19 inches, and the product description says it moves the tire-and-wheel assembly 3/16 inch inward toward the trailer frame.
Best for: Buyers whose trailer requires the specific single-wheel configuration and fitment listed. It was selected as another 17.5-inch wheel option, not as a tire recommendation. Limitation: It is a rim only. The supplied fitment details differ from the dual-wheel option, so do not assume the two wheels are interchangeable.
Buying Guide: How To Choose 9R 17.5 Trailer Tires
Does 215/75R17.5 match a 9R 17.5 tire?
Do not assume that two tire-size notations are interchangeable. Check the trailer placard, owner’s manual, current tire sidewall, or guidance from a qualified tire professional. Match the specified size and load requirements before buying.
How should you compare load range and ply rating?
Compare the tire’s load range and stated maximum load with the trailer’s required capacity. The listed GREMAX options are 18-ply rated and load range J; the Taskmaster is 16-ply and load range H. Ply rating alone does not establish that a tire is suitable for your trailer. Observe the correct single or dual configuration and pressure guidance.
Do you need one tire or a set?
Choose the single GREMAX listing when purchasing one tire, or the four-tire listing if you need four. Verify the package quantity and plan replacements according to the trailer’s needs rather than assuming a set is required.
What should you check before buying a wheel?
Confirm wheel diameter and width, lug count and spacing, hub-piloted or stud-piloted design, center bore, and offset. The two eCustomRim options have different fitment descriptions. A matching 17.5-inch diameter by itself does not prove a wheel will fit.
