garry taylor

Question

So

I have a Bedford MK/MJ with the standard bargrip 12.00 x 20 goodyear tires, i want to know if there is a european size equivalent...as im in Iceland.

 

eg the new metric sizes

 

also im prity sure i could change to 11.00 x 20 or 14.00 x 20...but does anyone know for sure...

 

but the main thing is...is there a euro/metric size that will fit bedford rims

thanks for all the links guys...but im more looking at what i can find in here in Iceland...to see what other types of tires will fit....as there are plenty of offroad tires up here but not 12.00 x r20....more the stuff for unimogs

 

im gessing that out in guyana they have the same issue, cheap latin american tires ( metric), but with british rims

 

 

the pis i see of guyana of the trucks...they deffantly look wider

As Terry and I said, though, could a local tyre dealer not get tyres the correct size from Michelin, Conti or another manufacturer who still does 12.00 x 20? Bringing them into the country would be their problem then, and done by the same mechanism they bring other truck sizes in.

Hi,

 

Last year I bought brand new 11.00 x 20's from our local tyre dealer. There was quite a choice from various manufacturers. I appreciate that wasn't in Iceland but the point is that they are available, as others have said.

I think you might struggle to find a metric equivalent. Most of the metric tyres have a different profile to the 12.00 x 20, so you'd probably have to go to 22.5" wheels or accept a much smaller rolling diameter and perhaps load rating vs. the existing tyres. I don't know whether that might be a problem under Icelandic traffic laws?

 

If there's a Michelin truck tyre dealer in Iceland, they still list a 12.00 x 20 in the XZL, but it won't be cheap.

 

Edit - as do Continental / Conti, in various ranges / tread patterns

 

Try Googling tyre size converter or commercial vehicle tyres.

 

1200x20 is a standard size which is why most manufacturers offer them, dropping down to 1100 x20 will lower the gearing resulting in a lower top speed. Michelin do a 365/80x20 which is only 25mm smaller in diameter to a 1200x20.

Ha Ha just realised I hadn't uploaded the tyre size table in my post! Post now edited. You can see the effect of alternative sizing by using lower profile 22.5 tyres.

 

22.5 tyres are tubeless and would require new rims, the rims on all military Bedfords are 3 piece tube type.

John, I think that's what I was trying to say when I referred to rolling diameter. 365 is a significantly wider tyre than 12.00 though, so Garry would have to check wheel fit and whether it would foul anything.

 

It still seems to me that the easiest options are to buy new, correct size tyres from an Icelandic dealer, or to import surplus or part worn correct size tyres; unless there's a significant cost restriction and Garry is trying to find common second-hand tyres in Iceland?

I can imagine why Garry is wanting to avoid using his bar grips on the snow and ice in his back yard! Not the best…..

 

How many trucks are there in iceland anyway? My guess is that all of Eddie Stobart's and Norbert Dentressangle's fleet combined would cause a nose-to-tail traffic jam around the perimeter road :-D

 

My guess is that there are no 20" tyres running commercially in Iceland. All trucks will be on 22.5" rims (or maybe the odd low profile if imported secondhand so fitted - not too many height restrictions over there). The possible exception might be military trucks on the USAF base on the island - there could be a source of 20" tyres there but might be bar grip?

 

As suggested before, purpose-made 22.5" tubeless rims with the correct offset will be expensive and almost as much to import as a set of tyres, you still need a matching set of half-decent tyres if they can be found locally.

 

I reckon cheapest solution would be to get a set (and a couple or more spares maybe) nice take-offs on rims palleted up for shipment. Try Dave Crouch. I'm now thinking around £1000 would be a more realistic price to see a set of 4 bought and delivered assuming a pallet costs about £400? (that might be way out of course).

they are 12.00 r20 and Michelin do you guys think they would be ok...possabley they are work vehiacls tires.... so i dont know if the tread is ok for a truck.....or if they take the speed/weight...any ideas...i know they look like the daf truck tires....but if you look close the tread is slichtly diffrent and goes straight

Quite possibly.

 

The 335/80 is equivalent to 13.00 x 20 but with a lower aspect ratio (80%) so will be very slightly smaller dia. than your 12.00 x 20s.

 

The 395/85 is equivalent to 15.5 x 20 but even with 85% aspect ratio will be larger dia. than your 12.00 x 20s.

 

Can I suggest you run the idea by a tyre fitter as the 395 might be too wide for your rims (335 should be fine). They'll have to have tubes fitted if using your rims.

 

Note that the Guyanans have cut the lower fronts of their cab mudguards to allow those bigger tyres to turn - you'll have to do same to rear of cab mudguards too, and also reset the steering stops to avoid chewing out tyres or steering linkage.

 

I borrowed a 16.00 x 20 XZL fitted to a TM rim and tried on my MJR with cab raised by 3" and it would not work, but maybe you'll just get away with the 395/85s as with the smaller aspect ratio they'll be smaller dia. ......

 

Best to ask to borrow a tyre and get one fitted to your rim so you can try it out first. Either that or get some dimensions and do the measuring accurately!!!

 

P.S. I've seen a Bedford running on 14.00 x 24 wheels so anything is possible, but I don't reckon they had a lot of steering lock!! It belonged to Rose of Kenton drainage contractors in Suffolk but I think they are no longer in business so you can't ask them how they did it.

the last photo i posted...which were the tires for sale in Iceland...they were a specilised tire for offroad forklift trucks,so they had a speed limit which was way to slow, eg max 25 kmh...sham as 12.00 are almost impossable to find out here in Iceland and the cost of shipping and import tax is too much for the tires (especaly as we are exporting the truck to africa) so looks like we will drive with the ones we have ( i found a 11.00 for a spare in case we get a flat) and will buy a new set in Morocco
