Thanks to you guys for the replies, it really helps me to make decisions I think..... The wheels on offer have now gone to four of, apparently the chaps dad fitted them to a cobbled together tractor he made some years back, it featured Landrover axles, hence the wheels. The tyres were originally for a Dumper truck, but that got cancelled and the old boy sort of acquired them eventually. They are Avon 7.00 X 16's on narrow width wheel rims removed from an old Landrover, Series 1 perchance.. ????????. They sound perfect for going into the woods this time of year however.... at least I now know what they are about even if they are mite ancient, but stored in the dry, off vehicle for ages and now up for grabs, so maybe I will indulge at the right price. The old boy used to have a Defender before he shuffled off the mortal coil hence the rather strange request, but thanks again, it helped me no end to know a bit about this..... my avatar is the offending vehicle of mine.. !!!
