Current tyre recommendations for big US utes?

Check out Coopers A/T3.. Light Truck. They have that size.

Cheers

Hi MattandLana,

Goodyear Wrangler Duratracs for my F250. they are 285 75 16 though.

Not sure they come in 18 inch either?

I could only get Goodyear Wrangler 245 70 18 for Jenn's Pajero, standard size, (not as raw a patten, as the duratac) but way better than street tyres, cost $500 each last year.

They wouldn't let me upgrade to 265s tried to tell me it would put to much extra stress on the gearbox? (I still don't believe them, just changes the power a bit & the speed reading a bit.)

Mickey Thompson have 275/70r/18 WE ARE GOING TO TRY ON OUR RAM

Hi Matt and Lana, I am going through the decision at the moment, as I would prefer to have a heavier duty than the Yokohama Geolander 265 70R17 on the Ram 3500 currently.

I am planning to go with Cooper S/T Maxx which I have had good runs in the past on the Landcruiser. I am trying to decide the extent I am prepared to go for gearing change. Options are 285 70R17 and a bit bigger in 315 70R17. The nominal ODs are 31" for the current Geolanders, 33" or 35" which would drop the engine revs even further at towing speeds. The 315 70R17 would provide an 8% gearing change. Speedo changes can be made through some tuners, like the H&S so you can keep the readings close to correct

One of the options for Rams is to go with 20" diameter wheels which opens up a whole different discussion, when challenged on the diameter change from your OE tyres or rim combination. We are to use the OE wheels. I have been told that the transport authorities do ask from time to time about wheels, but the 20" option tends to get them looking elsewhere

Have Coopers on the van, Had them on an F250 and have them on my current 200 Cruiser. Never had a problem.

Cheers

Before you go down the path of 20" check the availability and cost for them
I run them on my 350 and they are expensive with not a great selection available in Australia I believe coopers have brought 20 into the country recently so even though I don't need them at the moment I purchased 6

Hi All,

I would also caution about going to 20 inch. I run the radial TA on my F350 to get the required load rating but they need to be inported from the US and they also have a lower profile so you tend to loose some sidewall flex. I note that some other companies are starting to make the 20 inch but they are still very hard to get hold of. Had to wait about 4 months to get the last batch of 6.
Dont plan on getting a spare somewhere on the road, its not going to happen.

Re

Hi all, thanks for this input. I'd only change rim size and outside diameter if I had to. So I'm trying to fit my factory 18" rims with the same profile. Coopers and Mickey Thompson seem to do ones in Oz. Bridgestone no, and even Michelin don't, according to their websites. I'll ask of course, because they may not have all the odd sizes like mine, on their website. I'm just looking for feedback on the Oz-available brands first. Coopers ST/Maxx seems to be the Rolls Royce option.

John/Grumpy fair comment re the US forums, but I'm especially interested in Oz users. Less snow and ice in WA. We had some mud once.

I have recently purchased 2015 F-250 it had an 18 inch spare with 20 inch on vehicle, so 18 inch Michelin is for sale with F-250 steel rim (never used). Price 650 dollars. If you are interested ?

Quicksilver, were did you get the replacement 20 " from..
Have also just brought a 2015 F250 and would like an extra spare.
Just to make it more difficult mine is a Platnum model with the alloy wheels.
