HI GANG
is anyone out there running 235/75R15 tires on a bone stock 96 to 98 Suzuki 4dr Sidekick including stock rims?

I have 215/75R15's on now and would like to go to the slightly bigger tire but are there any issues with rubbing,etc. if I do??

on my 91 2 dr ran them for awhile till I lifted it there was no rubbing at all,  but some peeps have rubbing problems at full lock 

X2 agree.  The frame rub occurs when you fully turn either right or left.   One tire will rub on the frame at the back.  It causes no damage and isn't an issue other than eventually you might polish the paint off your frame there.  If you mount some aggressive MTs the rub may be more significant, but it is still totally doable and easy to live with.   You don't turn full lock that often anyway.

You might have to trim the bottom of the bumper a little bit, but other then that you should be ok.

Thanks guys - I was hoping they would work - according to the tire spec chart they are only 1.2 in more in dia. and a 1/2 in wider but???

do you know what the stock rim width is - 5 1/2"??

also - on another note - are any of you running balance beads in your Zuki tires???
I have them in my motorhome and they work well?

For that small of a tire I would just do a normal balance with a wheel weight.  If your worried about knocking them off then make sure you mark down the size and the location so you can replace them if needed.
