Trailer tire advice for a 5x8 ram trailer, For an ATV

I got an old 5 x 8 trailer to haul my can am outlander 2 seater, so a rather large ATV.

One tire is 205/70R14, one tire is ST175/30R13

I want to replace both tires with the safest option.

My mechanic says to find one 205 sized.

Also, where’s the best place to buy trailer tires around Toronto? I’ve bought some at princess auto, and was planning to buy another set from princess auto, but some people say that the quality isn’t the best.

Thanks

I buy some at princess auto befor they ok but not the best they more money but i will get 15 inc and be 8 or 10 ply them you be in good shape

Thanks Moose, any recommendations of the size of tire? Or where the best place to buy tires for trailers is? Thanks

You need to be sure and get ST rated tires. That stands for Standard Trailer. You aren't allowed to just use regular auto tires because it can negatively affect the handling. As for the size, be sure that whatever width you get leaves plenty of clearance between the inside of the tire and the frame and is small enough in diameter to allow for full travel of the springs and not rub on the fenders. Going to a 15" may be too large for the trailer so be sure to measure first. Standard two ply tires are usually okay, I have been using a set from PA for 15 years now but if you can find some 4 ply they will be a bit more durable, although the ride will be a bit stiffer. Even 8 inch tires will support the load of your quad but personally, I usually go for the largest tires that will fit the trailer. I find they last a lot longer than smaller tires. The larger tires also have lower rolling friction so your fuel economy is better. Hope this helps.

Also, the largest tire diameter you can get in there (and resulting circumference) rolls over cracks and bumps smoother and easier, and at less RPM, keeping bearings cooler - lasting longer

as said the closer to the same size as the pull vehicle is better, that way the tires are turning close to the same amount. Remember all tires have a life, which is I think 5 year. I know this only because I blew out a tire on my boat trailer and the shop couldn't believe I was still using the original tires that came with the trailer, which was 10 years. So I replaced both tires.

This is far more than enough for what you need in an 8x5 trailer. Trailer tires
Get 2 new ones and keep the older one as a spare. I've used PA trailer tires for many years and never had a problem with them. Check the 4 number date code on the sidewall to make sure you get new stock.

Thank you for the Information, I’ve been doing my own research as well, but your write up is very helpful.

I’ve settled on these: https://www.princessauto.com/st205-75r14-5-...ct/PA0008786402

I’ve decided to stay away from 13 inch and go for the 14 inch wheels and made sure they’re ST rated!

That is why I want to replace tires. I didn’t have a blow out but very close to one. When driving I noticed the truck shaking at 100km/h I figured it’s just an old truck. When I got home. This is what I saw.

You can buy from Princess auto but prior to mounting them get them balanced.....most people forget to do that and you will get a shimmy shake shake bouncing tire.
