I have standard (size) tyres and am carefully considering an upgrade. Everything is pointing to 235/85R16 being the best size to go for for me, but 7.50R16 is a possibility too. There seems to be not too much price difference either.
Think I'll give them a try, I've got 31x10.5 15's but finding them a bit wide, I can get most places but on slower tricky stuff and steep climbs they won't dig in .
The kingpin factory is only about 20 mile from here, might see what there like now .
