THOR MOTOR COACH | MADE TO FIT
Failure to replace damaged tires with tires of the same
size, type, traction, and load rating than the originally
equipped tires can signicantly affect the weight carrying
capacity, handling, and safety of your motorhome.
Ensure the spare tire is the same size and specications
listed on your motorhomes Federal Weight Label.
WARNING
Tire Replacement
Tires degrade over time depending on conditions they are
subjected to throughout their service life; such as weather,
storage, and conditions of use (load, speed, ination pres-
sure, etc.). In general, tires should be replaced aer six years
regardless of tread wear. Heat caused by hot climates or
frequent high-loading conditions can accelerate the aging
process and may make it necessary to replace tires more
frequently. Due to aging, the spare tire should also be replaced
when replacing the road tires, even if it has never been used.
All tires should be replaced with the same size, type, load
rating, traction, and temperature rating (or better) than the
original equipped tires. Tire specications are listed on the
motorhome's Federal Weight Label (Section 6) or found
within the chassis manufacturer's owner's manual.
The load index of tires configured as dual-wheels is less
than the sum of the tires. is provides a margin of safety
for load-carrying capacity in the event that one of the dual
tires is punctured or otherwise fails.
NOTES:
• The tires supplied on your Class C and some Class
A motorhomes carry a “Light Truck” rating.
• Installing replacement tires with a higher limit than
that of the originals does not increase the payload
capacity of the motorhome. Refer to the chassis
manufacturer’s owner’s manual for additional infor-
mation.
SmoothTECH
TM
Suspension
Select TMC motorhomes are equipped with SmoothTECH
suspension upgrades. is system adds rubber compression
springs to the rear suspension, allowing for longer spring
travel and reduced suspension harshness, which enhances
cushioning and absorption of road-induced bumps and
shocks.
Rubber compression springs give your SmoothTECH equipped TMC
motorhome improved ride comfort.
