This 8-ply radial tire and wheel combo is built to handle long hauls at highway speeds without breaking a sweat. The Kenda Karrier S-Trail ST145/R12 radial tire carries up to 1,220 lbs at 65 psi, with a speed rating of M (81 mph). The double steel belts and full nylon plies keep it stable under load, while the premium rubber compound helps disperse heat for better tread life on extended runs.
The steel wheel features a tough 8-spoke design coated in white powder over an e-coat primer to fight corrosion season after season. Its beveled stud holes keep the wheel seated tight against the hub so lug nuts stay secure without constant retightening. The wheel is rated for 1,250 lbs, has a 4 on 4" bolt pattern, a pilot diameter of 2.84", and a 0 offset for straightforward mounting.
The Karrier S-Trail tread is computer-generated with breaks in the ribs and fine sipes that channel water away from the tire surface. That means better contact with the road and improved traction when conditions turn wet, snowy, or icy. It’s the same kind of tread approach found on automotive tires—purpose-built for control and confidence when weather doesn’t cooperate.
Skip the mounting appointment—this tire and wheel come paired, pre-mounted, and aired up so it’s ready to bolt on right out of the box. The assembly meets DOT specifications and includes both a 5-year tire warranty and a limited 1-year wheel warranty, plus a 1-year worry-free guarantee that covers replacement if the tire is damaged within the first year.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

It has been a year of regular use with this Kenda tirerim combo and I couldnt be happier! They are still holding up great! Just made a dump run yesterday of fallen limbs from a recent storm.

Tires have been great. We have done at least a trip a month with out compare. We took it out to Iowa about 3k miles round trip and they have been fine. Our camper is rated for 2200lbs and I don’t think we ever push 1800-1900 so we are well below load rating. I think the “max speed rating” on the camper is 65, I have cruised at 70 and gone a little faster with these tires with no problems. The treads are holding up well. I plan to replace the ones touching the road every 3 years. I don’t believe they will be worn out by then, but that’s a recommendation from my camping group. They have had lots of blowouts and I prefer not to have that experience. If I had it to do over again, I would purchase this tire without hesitation.
