Tires are man’s best friend.
Big wheels and tires may look impressive but a BOV is
not a rock climber or a street racer.
So unless you plan to alter the drive train,
suspension and brakes of your BOV do not use tires which are more than 10%
larger than the original stock tires supplied with the vehicle.

Under normal conditions i use Cooper Discoverer 30x9.5 R15 A/T
tires on my BOV
However i plan to switch to Bridgestone Dueler 31x10.50 R15 A/T’s.
Both tires function very well in both street and off-road situations.
Note: It is the air inside the tire that supports the vehicle, not the

You can find this value on the side of the tire.
Also you could write it down on your lubrication chart for reference.
Determining Best tire pressure for your BOV
In a save situation you can determine the best tire pressure – with specific
load - using the following instructions:
First inflate your tires to the recommended pressure,
then place a chalk line across the tire tread.
Drive ahead a few meters and see where the line first wears off.
Too much air pressure and the center wears first, too
little and the outer edges wear first.
Keep experimenting until the chalk wear is even all the way across.
The result is your best all around tire pressure.
Check your tire pressures often with a good tire
Visual checks don’t work.
Keep in mind a tire rated at 2 bar will look about the same at both 1.4 bar and
2.75 bar given different loads…
It is very important to keep all four tires at the same air pressure for better
handling and safety.
A tire repair kit should be on your BOV outfit list.
Make sure that you have practiced fixing a tire using your kit at least once.
