When you’re logging serious miles with a heavy setup, you want a tire-and-wheel combo that’s built to take it. The Karrier ST235/85R16 radial tire is Load Range F with a 12-ply rating and a 3,960-lb maximum load at 95 psi. It’s matched to a 16" x 6" steel wheel rated for the same capacity, so both ends of the setup are ready for highway use. The tire’s M speed rating of 81 mph and DOT compliance give you confidence for long-distance hauls in heat or rough conditions.
The radial design couples strength with flexibility for a smooth, stable ride at higher speeds. With cords positioned at a 90-degree angle to the direction of travel, the tire flexes evenly, reducing rolling resistance and heat buildup. That means less wear over time, better traction in wet or dry conditions, and improved steering response when you’re towing down the interstate.
Moisture and road grime don’t stand a chance against the white powder coat finish over an e-coat primer on this Dexstar 8-spoke steel wheel. The corrosion-resistant surface keeps the wheel looking clean and strong through rain, humidity, or coastal salt exposure. It’s a simple way to add durability and clean styling that holds up trip after trip.
No need for shop time before getting on the road. The Karrier ST235/85R16 comes pre-mounted on its 16" white steel wheel and arrives inflated to proper pressure. The tire’s heavy spot is aligned with the light spot on the wheel for a balanced feel that’s ideal for trailer use. Stainless steel valve stems rated for high pressure (up to 100 psi) come installed, so you can bolt it on and get rolling right away.
Fitment is straightforward thanks to the common 8 on 6-1/2" bolt pattern and zero offset design that centers load evenly across the hub. It uses wheel bolt sizes of 1/2"-20 or 9/16"-18 with a pilot diameter of 4.90". With an outer diameter of 31.6" and section width of 9.37", this assembly keeps dimensions consistent while delivering serious load capacity in a durable, worry-free package backed by Kenda’s 5-year tire warranty and limited 1-year wheel warranty.
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"

Fast ship and great value
Great Buy!!!!
The tires were delivered and they look great! Great price, great product, excellent service.
Very happy with the product and the ser vice.
Fast friendly service. They have been cummunicative the whole time
I ordered 4 tires on rims. Received promptly but noticed wrong valve stems installed. Called and etrailer sent correct ones and gave credit to get them installed. Took tires for valve stem installation and had tires balanced. 3 were fine but 1 rim had 2 inch runout/wobbled. etrailer made it good by sending a replacement. Etrailer treated me right but 2 different problems with one order will keep me from ordering from them again. If I had installed tires without the balance/problem discovery if would have tore my trailer up.
Good quality, excellent value!

so far so good. trouble free summer
We just received two tires for our trailer. We have not used them yet to see how they will hold up to our load. I am hoping they will do well. If so we will be ordering again if we aren't in a hurry for them. The only think I'm not satisfied with is how long it took for them to ship. We placed our order, on a Monday morning May 23rd and they were not shipped out until, Friday the 27th. We finally received them on Wednesday, June 01st. Most of the time when you order something online it is shipped out within a day or two not four days later. It took a little over a week to receive the order that I feel like we should have had no later than the 27th instead it was just being shipped that day. If you are in a hurry needing tires you better go to your local tire store.
High quality tread, they should do well in the rain, mud and snow.
It looks like it will be a great spare tire. I ordered it Monday, and it arrived on Wednesday afternoon. It was a great experience.
Needed a spare for a heavy duty trailer I bought this is a great price and FREE shipping! The wheel pattern or design is a perfect match, I'm a happy camper!

I am looking to upgrade my trailer wheels and tires from 6 lugs to 8 lugs to a st23585 16 14ply tire and I need to have the tire to move out from the springs about 1/4 of an inch. can this be done. Thanks, Paul
