Michelin XZY tires need replacing

I'm in the UK and just noticed the outer rear tire is cracking so checked the date and they are 2002!!! They are Michelin XZY 122/121L 14PR and are 7.50R16 size but I can't seem to find anything identical now only Land Rover tires but these are XZL so not the same. What is the equivalent size as I don;t want to drive it now I've spotted this.
Has duellys on the rear (single axle) and single tiree up front, Itasca Passage 1995 25RU weighs just under 12,500 pounds.

Just checked the other side and its dated week 28 1998!!!, although no cracking. It was imported to the UK in 2004 so has the US spec tires all round.

I’d be more inclined to check with a knowledgeable Michelin tire dealer in the UK for a replacement that would suit you now as well as on the road if need be in the future.

I'm sure someone still makes a biased ply radial in that size. The metric equivalent might be something like 235/85 16. The new size is an inch wider which does raise the undesirable possibility of the inner dual sidewalls rubbing together.

My concern was finding the right load range on a tire for a class A in an antiquated size.
Mine are load range F which translates to a 14 ply strength rating even though the tire has only 4 outer plys (I think).

Seeking the advice of a truck tire installer is sound.

I'd be weary of online tire purchases but I would think Amazon or EBay could ship overseas if you wanted the original size.

I've asked the seller what the date of manufacture is as been caught out with this before. The tyre i'm looking at is 12PR and not 14PR - is this an issue? Also some of them appear to require a tube and some are tubeless. I have tubes on my 1974 Land Rover so familiar with them.

I helped out someone in the UK with this issue last year, They have a 1995 Itasca 23. The original 7.50/16 D is now metric sized to 215/85/16 with a max load of 1216 kg That is what Michelin will spec in the USA. The closest current Michelin equivalent in the UK is the Michelin Agilis Camper in 225/75/16 (load 118)it has a max load of 1320 kg per tire. The only physical difference is the ride height/ground clearance will be 1/2" less with the 225/75/16. The section width is about 5/16 greater but the rear dual tires will not rub on each other.

Here is a link to the source he said he bought his tires from https://www.clitheroe-tyres.co.uk/Ty...mping+22575R16

I wanted to mention that the Agilis when we researched it the recommended load was 116, when he bought the tires the dealer strongly suggested he go up to the 118 load for durability.

Many thanks Rick. I'll see what is about. The seller in surope came back and its a 12PR (ply rating) and they couldn't give me an exact date of manufacture but would say it was less than 3 years old so I'm not buying from them.
Interesting - states 121 load index.

What about 215/85/16?

Interesting that you can find in the UK/EU higher load rated tires for the same size tires than in the US. I was looking at the 215/85/16 size from the website you linked,Unless I'm reading it wrong that size only shows a 115 load rating, You need 116 at a minimum.

Measured the tyre (Michelin) and its 200mm wide worst case. A 225 on the rear would be too wide and the 2 duals would touch or it would be very close. Nothing really in 215/205 at that load rating. Really struggling now with the rears. Was the original fitment 7.50 R16?
I've got 7.50R16's with inner tubes on my Land Rover but only 112 load rating.

Michelin have come back to me and suggested I go for another brand, they suggested a tyre from Hankook but they don't make it in my size.

I tried to find contact information for the guy I helped with his tires last year. I no longer have it, All I know about him is he was from the Leeds area. He said the Michelin tires did not touch each other when he had them installed. Have tried posting this question in any of the UK Caravan forums?
Sorry I can't help you more.

Thanks Rick. I can get the 225/75/16 in 121 load rating - Michelin Agilis +. There are 2 on ebay, brand new, and only £70 each so I'm going to try those on the dual axle and see how I get on. If not I can sell them on. I've checked and there is about an inch gap between the 2 bulges on the tyres so 225 will be tight. I've checked the 225's on my TVR and there isn't as much of a bulge so they may be OK. I'll let you know how I get on.
Any idea on wheel nut torque??
Luckily I have a 1" socket.

Wheel nuts are 145 ftlbs by the owners manual, I have using 160 ftlbs. If the tires were not to work you can always use them on the front. Good luck!

BTW in case you don't have this.. It will answer a bunch of questions.
