Young bobtail Rhys Posted January 27, 2008 Share Posted January 27, 2008 I would say anything between a 7" to 10" would fit, but the rim which would perform the best would be around 8-8.5". As for off set I am not sure, you may be looking at around +50mm each side, but I am sure someone will correct me with better experience. What tyres are they, simex et2?

jimmy mad Posted January 27, 2008 Author Share Posted January 27, 2008 cheers why want a 10 fit ?? Quote Link to comment Share on other sites More sharing options...
l4ndymac Posted January 27, 2008 Share Posted January 27, 2008 The recomended rim size is 8" to 10", sorry cant help with offset . I was looking at some of these. But with some of these Range rover sport 20" wheels with 33/13.5/20 tyres. Quote Link to comment Share on other sites More sharing options...
Young bobtail Rhys Posted January 27, 2008 Share Posted January 27, 2008 A 10" would fit but the off set would be very high, and the side wall ends up a bit flat. Not sure if that will affect performance or not? Quote Link to comment Share on other sites More sharing options...
jimmy mad Posted January 27, 2008 Author Share Posted January 27, 2008 i need them to be modular as i want to make them into bead locks any one no a place to get 16 10 modulars from Quote Link to comment Share on other sites More sharing options...
Young bobtail Rhys Posted January 27, 2008 Share Posted January 27, 2008 I have some 7x16 modulars and next thursday they are going away to have external beadlocks on as well. This increases the rim width from 7" to 8.5" or there abouts. I will be running 35/12.5r16 maxxis cc. What tyres are you planning on running, some tyres are generous in their sizes and others aren't. A 10" rim with a beadlock is very wide ~11.5". Devon4x4 do the 10" wide modular for about £45. My rims were just £34 as they are much narrower, but with the beadlocks they work out as the right size.

Defender Posted January 27, 2008 Share Posted January 27, 2008 A 3.75" back spacing should be ok for that size of tyre. Depends what your intending to do with your tyres but something to think about if using single bead locks & airing down your tyres is a 7" steel disco rim has a very deep inside lip which means you've got to push the inside bead of the tyre about 4" before it drops into the wheel well. This makes them ideal for making single bead locks as it gives some protection to the inside bead & makes the rim 8" wide when the bead lock is welded to the outside. You will still need to use wheel spacers to get the correct offset but the rims are available very cheaply second hand on a well known auction site. Obvioulsy not quite as good as double bead locks but as we can't all afford to import them from stazworks this is a very viable option worth considering.
