225/75r15 on merc steelies 7j 15 25mm offsett, 4mm poke, folded the inner lip a little and spaced the front bumper forward a little and trimmed and plastic welded rear bumper a little, still need to lift itt 30mm, but not really neccesarry,
I took some 35mm offset rims to replace the 55mm offset and then added 7mm more in spacers. I've wound the front tortion bars about 75% the way up, put airbags in the back and knocked the guards out a lot. It still bottoms out when bouncing over bumps at speed and scrubs a little when on full lock left. I plan to fit 20mm spacers at the front to replace the 7mm ones, flare the guards more and wind the tortion bars up more.
I should have mentioned that it scrubs on the left turn because there is a fuel tank vapor sub tank in the wheel arch, I had to move something in the right arch that was connected with hoses, maybe an oil catch can or something, easy to move, but the fuel tank vapor thing is not an easy move. I'd think its a new fuel tank to move it. It has a metal protective plate on the front so it's hard to damage.
Thing is, here in Norway, the LAST thing you use for winter is "Chunky Tyres"....
We use tyres with around 10mm tread, with LOTS of thin "snipes" on them to remove snow and ice.
I'm talking about an area in Norway where they plough the roads "down" to leave a couple of inches of snow...to provide "grip"!
No-one uses chunky tyres unless for mud.
Also...using different tyres front to rear, would have you walking home and your van impounded until you fit 4 tyres of the same type...if stopped by the police.
Front and rear tyres should be the same.....or maybe you enjoy having the a$$ end coming in front of you if you have to brake suddenly?
OK....I use studded winter tyres, but they only have 10mm tread, and hundreds of small "slits" in the tread.
