BAXRTUTE Gold Donating Members 2,639 Member For: 9y 8d Posted 18/10/16 09:51 PM Share Posted 18/10/16 09:51 PM A few months ago I got some Simmons 20/10 concaves I have rapped them in 295/35 now the tyre is streched at least 10mm each side of the rim. Yesterday I emailed Simmons on the exact size of the rim. After 8 emails of the guy trying to not answer he finally came back with the rim size actually being a 20/11 inch which now makes sense of the tyre streching as much as it is. I had looked and ordered some MT semis 305s but cancelled due to not being sure it would fit and wasting $1400 on tyres. Thinking I mite try get a R888 315 on there now that ive been told its an 11inch wide rim. Thoughts tyre gurus ?

Hey, how about you send me some high quality 19" tyres and I'll report back with my testing? Isn't the R888 discontinued, replaced with the R888R?: http://toyotires.com.au/tyres/motorsport-tyres/item/1250-proxes-r888r mmmm I'd love a set of these but I'll probably be going for a set of cheapo tyres cause I like spinning them.

I had retreads on a off road dirt bike that were good (came with the bike). With 315's on the rear, especially r888r I think you shouldn't have too much trouble getting traction which should allow you to run a decent qtr time on them, considering it's a manual.

BAXRTUTE Gold Donating Members 2,639 Member For: 9y 8d Posted 18/10/16 11:01 PM Author Share Posted 18/10/16 11:01 PM (edited) Im gonna try get a test fit done of a 315 before buying. But would be stoked if I can get the toyo 315 on as in most eyes there the best. Traction is always going to be an issue with close to 500rw wasps and a trillion nm to go with it.

I think you'll wind up with a bit of sidewall role. As an example i've got a set of A048 in 265/35/18 and the tread band is aprox 270 plus the shoulder width. Anything bigger then 295 in a semi is going to need surgery to the lip on the rear guards. You can't roll that on a ute so you'll need to trim it with le ol' grinder 1 Link to comment https://www.fordxr6turbo.com/forum/topic/92567-simmons-fr-c-cconcave/#findComment-1617290 Share on other sites More sharing options...
