Unimog U1300L Year unknown, but it has a Bundesheer rebuild plate dated 96
Gentlemen, I have posted before about my search for The appropriate tyres for my Unimog 1300L here in Poland. I am finally getting closer to the tyre choice that will fit my needs 'in the long run' and be cost effective. As I posted before I was offered some Russian 'Forward Traction' tyres as fitted standard to 'Kraz' and 'Ural' russian military trucks. The tyres were beasts with a heavy MPT Tractor like tread (which I need here in this clay soil) They also stood much taller than my Michelin XZLs in a 12.50 equivalent size, probably due to the massive depth of the treads. I tried to fit these tyres but was foiled by the valve position of the Unimog 6 stud wheel, the heavy rim of the Russian tyre would interfere with the valve operation and may even have popped it out under heavy flexing. OK.... options suggested were have the rims cut and moved and the valve hole moved. Good suggestion, I think from Normalbloke, many thanks it is still an option. But better yet I have found that there is a massive supply of split rim (Bolted...many bolts like 'custom' alloys) wheels which are/were fitted to the 'Star 266' Poland,s 6x6 answer to the Unimog 1300L.....only problem is they are 8 stud. So my new option is a one off payment to have 4 adaptors made (cheap here in Poland) I can then fit the 8 stud..'Star' 20" wheels....which are built for the Russian Tyres in the first place.....another benefit is that I can change my own tyres with little difficulty due to them being bolted split rims. (I intend to keep this Unimog for many years, so changing my own tyres is an advantage that will pay off in the long run) Now I have just found that the Poles do a copy of the Russian 'Forward Traction' tyre, it is called the STOMIL T45....made in Poznan....in 12.00x20 or 14.00x20. Now what puzzles me is that some people on this site have stated that they fit 14.00x20 tyres on 6 stud rims and have no clearance problems.....well they would with these Stomils!!!!! the 14.00x20 Stomil T45 has an overall diameter of 1260mm which seems altogether way too BIG for my U1300L..and it is 420mm wide (this is the size that is fitted to the Russian KRAZ 10 Tonners) so my question to you Tire Wizards is this: will the 12.00 x20 Stomil T45 be a good option? (will it comfortably fit under my wheelarches?) it looks like it will, here are the specs 12.00x20..... 10 Ply rating.....minimum rim 9.0x20...... Overall Diameter 1130mm......width 330mm....Speed rating 85Kmh......certified for use with onboard tyre inflation systems...(Not that that Poles bothered with that much complication in their home built trucks.) This Stomil tyre is going to be cheaper than the Russian version and probably 'e' marked = for sale and fully safety tested in Europe = stringent testing) ....it solves the speed problem I currently have with the Michelin Power CLs and is a Much taller tyre. (Thats a part of my question for you Tire Wizards...."how come this is a 12.00x20 Tyre and my old Michelin XZLs were supposed to be 12.50x20...yet this and the Russian tire and the Polish Stomil is wayyyy bigger in overall size (almost fills the arches in 12.00x20 and is obviously much too BIG in 14.00x20 size??? (Though I have to say that the pics don,t do the 'lugs' on this tyre justice they are every bit as big as any I have ever seen on a true Agri Tractor tyre)). Lots of questions here....I hope I havent complicated things too much? I thank you in advance.
