hi guys my truck is going to live in a new home.

from sunny california to smoggy streets of tokyo and now to the snowy mountains of northern japan

snow being the issue

the white walled firestones have zero grip!

i need to get some bigger more grippy tyres for the snow


can anyone advise what is the widest tyre size front and back i can fit on a stock 49 3100?

unfortunately i cant measure the truck as its already up there.

i need to keep the dia unchanged just wider, can live with offset change as needed

any advice appreciated

cheers
mike
