Recently started to look at sorting an old family tractor Forson Major Petrol TVO 194X. All in all pretty good order the first problem however that I am faced with, is that it needs a new rear tyre, no that sound quite easy until I realised that the rear wheels are reasonbly rare....they are somewhat thinner that the average Fordson Major. The tyres that are on at the moment say 11-36. however the rims are only aprox 10 inches across. The everyday tyre seller wants to sell me a 12.4-11-36 but these I am told will be to wide on the rim. Can anyone help...has anybody experienced this? How did you resolve.... I guess I could source a replacement set of wheels and tyres but I would like to keep it original. Any help appreciated.
