Hi there Guys, new on here but was hoping someone could help me...looking to buy some new wheels for my vitara jlx....i quiet like a look of a pair on ebay( http://www.ebay.co.uk/itm/Suzuki-Grand- ... 2c7458b91e ) was wondering would they fit my normal Vitara with them being grand vitara wheels and also would they be to big as my vitara is standard with no modifications. thanks guys x

I would say too big for a standard vit

I'm pretty sure 235/75r15 are a squeeze on a standard vit and those work out around 1" bigger.

Had 235/75/15 on a standard for few weeks, insa turbo Sahara. They rubbed like fooooook don't do it. Mine rubbed against chassis leg on lock and got little to no flex on the back and with front anti roll bar removed they rubbed over every bump under steering!

I've got 600/16 tyres on my wagon at the mo,ment, this was the original size it had. what's the metric equivalant of this?
