what's the best tire 205-75-14

[jlgail4309]

I'm looking at Kumho 857 tire. I'm wanting a good tire that will run at 75 on the highway. Thanks for all the help.

The Kumho 857 isn't offered in the 205/75R14 size to my knowledge. These tires are what we called Euro-sized and the one that says 205R14 C would be kinda equivalent to a 205/82R14 (which is taller).

Hold on and I will find a better sizing explanation between them.

I travel most any were. But I'm not doing 75 all the time but going down the back side of a hill. I might let it roll a little but 70 most of the time. Thank for getting out of the way . Do have a good tire to suggest. Thanks for the help

I prefer GY Marathons.

Here are links to the Kumho 857 specs and the Goodyear marathons specs, so you can see what I was trying to explain in the above post about the difference in sizing between the Euro-sized and the ST metric sized tires.

A Euro sized 205R14 C is taller than even a ST 215/75R14 metric sized tire.

I don't know how much clearance you have for taller tires. If going the Euro-sized route, you may possibly want to go to a 195R14 C tire to keep things closer to the 205/75R14 height, if that's what you have currently.

Looking at the specs a Euro 205 carries 2271 lbs while the Euro 195 carries 2094 lbs.

Either one of these is better than a GY ST 205/75R14 at 1760 lbs or the GY ST 215/75R14 at 1870 lbs.

Hopefully, I'm not boring you to death.......and you can make an informed decision that works best for your situation.

Thanks for all the help. I'm trying to find the best tire possible for my trailer. I seen a trailer at the camp site last weekend and it was ugly. It had a blow out and it tore it up. I think the Kumbo is a good tire. Not sure its the best. Hoping for people will have more input.

Maxxis has a C-rated tire in that size, with a load capacity of 1760 lbs at 65 mph.
If your load is less than that, you can go faster, as Maxxis tires have a high-speed rating.

The 195/82/14 D-rated Kumho 857 has a nearly identical circumference to the 205/75/14. It also has a higher load capacity as well as a 99 mph speed rating. I've made this switch and it works great.

I would nor recommend towing at 75 mph though . . .

[bakken]

If Kumho has a D-rated tire in that basic size, I would think that might be the way to go. I assume your camper has a single axle?

[jlgail4309]

Yes it a single axle trailer. It weighs about 3000 pounds. I would like to over rate the tire. Than have a tire rated for 65 and run that all day long. Some times the tires get so hot in the heat in Okla. You can even keep your hand on them. But I do hit speed of 75 from time to time.

I've ordered a set of Goodyear HMG2020 tires in this size for my Roo 21RS.

It was down to the Kumho 857 and these GYS for me. I didn't want to go with load range C tires, eventhough the GY Marathons get good reviews, and no tire shops up here in Canada seem to be able to get their hands on Maxxis tires. The Kumhos were from tire rack, and we're hundreds less, but then I'd have to find someone to install them (numerous tireshops said no), and I wouldn't have access to a network of tire shops across the country if I needed a warranty replacement while traveling. So I'll bite the bullet & spend more, hoping to get the safest & best-warrantied tire available for our trailer. And as an added bonus, someone has said these are made in Canada, so I'm happy to be able to support a North American factory!

I'll report back once I have them installed, but they look like the sturdiest tire to be found in this size, from what I can tell. (UHaul uses these tires on their trailers, so they need to stand up to all kinds of abuse!)

Needless to say, get them balanced by some means.

I plan on it, thanks OC!

I have new unable to find where it says Maxxis are high speed rated. Being an ST tire I was under the impression the they were speed rated at 65.

There was a recent post by wmtire where he emailed Maxxis and was told that by them. I can't easily search from my phone or I would- but, look him up and look for a recent post (last 3-4 days) by him.

Bobby,
The spped rating on for the Maxxis M8008 ST Radial is "Q", which is 99 MPH. However, according to the Tire and Rim Association the inflation pressures and load specifications in general for all ST Radial trailer tires, regardless of the manufacturer, are designed and rated at 65 MPH. If the speed is higher than 65 MPH, the pressure and load need to be adjusted according to the following guidelines:
From 66 to 75 MPH – the tire inflation pressure needs to increase 10 PSI (not to exceed the maximum PSI the tire is rated for) but requires no load adjustment.
From 76 to 85 MPH – the tire inflation pressure needs to increase 10 PSI (not to exceed the maximum PSI the tire is rated for) and load should be reduced by 10%.
We hope this information is helpful. Thanks for your email and interest in Maxxis Tires.
Best Regards,
The Maxxis Support Team

So if you start out with the tire inflated to its max you're good to 99 mph!!!

Maybe if you were 20 or 30% under the max load.
But I don't think I would push it.
It is just good to know that if you have Maxxis tires on your camper, you aren't forced to drive under 65 mph. Or if you drive at 65 mph all the time, you aren't on the edge of their rating.

The Goodyear HMG 2020, size ST205/75D14D are bias ply tires with a maximum load capacity of 2040. The tire has a “J” speed rating (62 MPH).

[jlgail4309]

I wonder if all the blow out are a tire rated at 65 and loading to the max. Then running 65 miles per hour for hours on end. After seeing the trailer last weekend . And pulling a deformed tire off my trailer. For safety we needed some better tires. Thanks for all the input and help. I believe the Kumho 857 is the only one I have seen with a speed rating over 65.
