standard rear tractor tyres are all with the v shaped grip pattern, here comes the bad news they cost a bomb, because of the cost of oil/ plus vat going up. Just bought 2 new rears for a fordson major im doing up and it was a struggle to get tyres under £200 each. thats not including tubes vat or fitting. so if your only needing them for farm duties and not much road work go for second hand although even used tyres have shot up in price. tractor tyre prices are currently still increasing per week. good luck hope i havent been to negative!!!!!!!!!
