Tires For All Types of Trailers
Have a landscaping or roofing business? Trailer tires are often neglected and seem to go at the worst times. Something we all see on the highway as trailers are left on the side, waiting for assistance. Bringing trailers to the tire shop is always a hassle. Let On The Spot come to you and don't loose any downtime with the trailer or personnel. We can handle the smallest tires to heavy duty 16 ply's.
Why are Trailer Tires Marked ST?
'Special Trailer' (ST) tires have been constructed for better high speed durability and bruise resistance under heavy loads. Trailer tire construction varies substantially from automotive tires, therefore it is essential to choose the correct tire for your towing application. In general, trailer tires have the same load range (or ply) from bead to bead. This allows for a stiffer side wall which provides safer towing by helping to reduce trailer sway problems. The use of 'Passenger Car' (P) tires a on a trailer is not recommended because their construction allows for more flexible side walls. This could lead to increased trailer sway and loss of control.
Always choose the right load range for your trailer.
Tire 'load range', or the maximum weight each tire can safely support, must be considered when selecting the proper size tire for your application. The load range and maximum weight capacity are indicated on the tire side wall.
LOAD RANGE B = OLD 4 PLY RATING
LOAD RANGE C = OLD 6 PLY RATING
LOAD RANGE D = OLD 8 PLY RATING
In general we recommend the highest load range rating available for any specific size. Cost are usually very close between load ranges.
Bias vs Radial Tires
Bias Ply Tires differ in the way they are constructed as well as the materials that are used.
Contrary to belief many new trailers still come with Bias Ply tires from the manufacture. We normally recommend that radial tires are installed when new tires are needed.
There are a number of benefits to the Radial design.
1) Softer, smoother, quieter ride
2) Improved fuel economy
3) Flat, wider footprint for better tire wear
4) Runs cooler than a bias ply, minimizing risk of a blowout on the highway
5) Longer tire life
6) Better tracking – Improved sway control
The main benefit for the Bias-Ply design is that the sidewall is more rugged and bruise resistant, plus Bias-Ply tires are usually less expensive. This could be an important consideration in a trailer application because many trailers are used infrequently, minimizing some of the Radial’s benefits.
Please include tire size when requesting information and pricing. Example: ST205/75R 16 or 205/75D 16 (bias ply).
