Spacers needed? 18x8.75 35 offset rims and hub centric rings

Post by erfdan »

Hey, I'm not really sure how to calculate this but if someone could send me to the right direction, it'll be greatly appreciated.
I have bought 18x8.75 rim's with a 35 offset (xxr 527). They seem to fit fine on the front with 225/35/18 tyres but on the back they scrub against a little on the inside. Would anyone know what length spacers I would need or a site or something where I'd be able to find out?

Also I have researched and found out that our centre bore is 67.1 while the rims are 73.1, would I need something like these to fit (even though the centre bore seems different in the picture compared to the ID http://www.ebay.com.au/itm/222479081507
Or could I use this spacer with http://www.ebay.com.au/itm/322361052588
This Hub centric ring http://www.ebay.com.au/itm/200920565934.

I'm kinda new to all this so any help is appreciated.
Thanks!

http://www.willtheyfit.com/ is your friend. I suspect they're probably hitting the rear trailing arm or pretty close to it. I'd say probably about a 10mm spacer on the rear would suit you about right. Are your guards rolled?

Hubcentric ring not essential but wouldn't go astray. Not sure how that would work with the spacer though.

Yeah youre right, its touching the trailing arm, my guards arent in contact with the tyres so that shouldnt be a problem, it seems to be only the trailing arm. Would i run into any problems if i just use a spacer and dont implement any hubcentric ring to the rims? (other than vibration over 80km).
Thanks for the link btw

Thanks

Wheels are meant to be hubcentric for a reason.

If they aren't, you're putting all the stress on the studs instead of the hub, which can mean bad news.
