General grabber tyres

235/70/17 will be +124.0 mm bigger in outer diameter than 205/50/17. it means that your gears are also going to be 20% longer/bigger. Speedometer has to be adjusted also.

I have m59 berlingo with 195/75-16 tires on gloss black alloys. I don´t remember which tires those are but it´s studded Goodyear with rough tread profile. Summer tires are same size but with smooth tread profile. There are some modifications done to fit those. Biggest downside is that the car is very fast on first gear.

Hi, on a similar vein I'm hoping to put some heftier tyres on my 2017 L1 Berlingo van. Reason being navigating access lanes to local hills - snow and ice to ski in winter, water and mud to bike in 'summer'. Winter rated (to run year round) and a bit of extra height would be useful to get over the crests of ice in the lane center. Currently on stock steel wheels with 195/65/r15 tyres. I've no idea how large / wide I can safely go without having to modify suspension / arches etc. I was looking at BFG KO2 tyres - seem popular in the camper van / off-road community. 

Any experience / advice on sizing and wheel compatibility would be much appreciated. 

Cheers,

Pete

go with large narrow tires like 185 or 195 if there is no terrain where the wheel might sink. narrow tire performs better on snow and water. wider tire "floats" better on soft surfaces.

as said, there is tools on internet to calculate size differences. I have modified suspension and inner fenders to fit tires that i have.
