Difference between car/truck and trailer tires?

[lewis15498]

Just picked up a 6.5x12 Bri-mar single axle trailer for my landscaping business. It needs tires, it has the standard white trailer rims with st205/75R15 trailer tires on it. So the question is can I go to the junkyard and just grab a couple 205/75R15 tires off a car or truck, or do i need trailer tires, if so what is the difference between the two? If anything i would think the car tire would be superior.
Thanks in advance for your input guys!

i think its a funky tire size and it might be tough finding them at a junk yard. though, car tires would probably work, and i have seen it done before, i think the main difference is that trailer tires have much stronger sidewalls. the biggest reason i would say not to do it, is in case you ever had a blowout that caused an accident or even if you were to get stopped by the DOT, i would think it would be a ticket for not having the proper tires. not 100% sure though. this thread makes some good points:

205/75R15 is a common sized tire used by 2wd tacomas s10s rangers exc.

I did some quick reading, so don't flame me if I get some details wrong...

Yes, trailer tires are different... but like car tires, they come in radial flavour and bias-ply flavour, and don't mix the two.

I think whether or not you want to use a car tire depends on what you're pulling. If it's a light load, car tires should be ok. If you're loading it down to the max and yanking it across the country, get the good ones. 205/75R15 tires likely never came on a vehicle over 3000lbs, so putting them on a trailer for 5000lbs and then towing it at highway speed is asking for trouble.

yes they are definatly different. trailer tires have a non agressive pattern that wont grab ruts in the road, they also have thicker sidewalls for both loadbearing charecteristics and tracking properties. get the right tire so you are not a hazard to us all.

lowes, home depot, and most tractor/farm stores have them already mounted for less than 60$
