hey guys,

i have tried searching already but didnt come up with much bout tyre size for trx wheels on a ute,

seen one bit bout running 185 40.. at the moment i got 13's and there 175 70 or 70

but at the same time they scrap on the firewall.

so has anyone got tyre size they ran?

With absolutely no supporting evidence I would recommend 195/45s on the front and 195/50s on the back.

maybe a leeeeetle off track but check this
tyre sizes

may give you an idea of what is close to what your running now

yeh i no of that site, but the reason im asking as i said coz the tyres i got now on my 13's scrap on the firewall

if you've got the bare rims ready to go, maybe go to a small tyre shop on a slow day and see if they'll trial fit a few different sizes for you to see what works best. A couple of shops in canberra have done that for me and seemed happy to do so.

U can go down to a 165/50/15 if you want something real close to the original rolling diameter, but a decent brand 195/50/15 will work, thats what ive got on my ute, but it every so often touches the front bottom corner of the wheel arch of the guard. I run a stanza front disc set up atm.
You could also try a 185/55/15, im swapping to these, i just have to fit them. U could even go for a 175/55 i think.

Ultimately i would be fitting the 165/50/15's on the front(potenzas) and probably 185 potenzas on the back or maybe a 195/45 as they are grippy and you dont really need much more with a decent tyre, but they are up around the 200 mark a piece. But u will generally need to order them in so testing may not be an option. Most tyre shops wont carry the more uncommon sizes, but u can get them.

i run the same 195/50/15 on trx rims with stanza struts, its rub a couple of times on decent lock with a big bump, just touches the paint. I put the 12" kidney beans on today and actually liked the "feel" of them a lot better.

On my ute with 120Y struts I ran the 195/45 rubber with no probs.

I wanted to go 185/40, but the price was off putting. Something like $40-$50 more each, and I get my tyres cheap.

i have tried both 195/50 and 195/45s on trx rims and found that the 195/50 did hit on the front edge of the gaurd. im running shortened stanza struts and lower control arms. so my recomendation is 195/45r15.

I have run 185/55/15 front and 195/55/15 rears with no probs , i hadm disc brake front end using stanza struts.
