When you’re towing serious weight, the Westlake ST235/80R16 Radial Trailer Tire holds its own. With a 14-ply rating and a 4,080-lb maximum load at 110 psi per tire, it’s built for trailers that see real highway use. The radial construction uses double steel belts and double polyester plies for strength and a smooth ride at speed. It’s rated for up to 75 mph (speed rating L) and meets DOT and FMVSS specifications, so it’s ready for long hauls with confidence.
Heat buildup is the enemy of any trailer tire, especially on long runs or in hot weather. This Westlake radial design places the cords at 90 degrees to the direction of travel, reducing friction inside the carcass so it runs cooler and lasts longer. The nylon tread-firming belt overlays help prevent tread separation, while solid continuous ribs add stability and even wear mile after mile.

Flat on the road? This tire includes complimentary roadside assistance for 2 years through Lionshead. If your trailer has a flat anywhere in the United States, Canada, or Puerto Rico, help is only a phone call away—24 hours a day, 7 days a week, all year long. It’s backup that adds real peace of mind when you’re traveling far from home.
The Westlake ST235/80R16 comes with an 11/32" tread depth and solid ribs that deliver consistent contact with the road. The tough compound and reinforced sidewalls help resist wear under heavy loads. It’s backed by a 5-year warranty from Lionshead, so you know it’s made to hold up under real-world use year after 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"

To be honest it is not unusual for the tires to be up to 2 years old. They are stored in climate controlled warehouses to make sure that they do not experience rot. In case you are worried about warranty, I can tell you the warranties on the tires start from when they are purchased and not from when they are manufactured.

It’s been very good so far, we traveled from the South to the West Coast from SoCal to Seattle and back. Utilizing the right tires combined with TPMS and travel speeds of 65-70 mph definitely works well.
