vtec2011 Posted January 21, 2013 Share Posted January 21, 2013 I got these TSW Stealth alloys and I had them on my Civic for a couple months.. They rub on the inner arch and bottom suspension arm when on full lock. I thought its because it got huge tyres on (205/65/15) So will lower profile tyres stop the rubbing or are the wheels too wide? I did look at the offsets on here but now I'm all confused! Any help will be great! Cheers... Quote Link to comment Share on other sites More sharing options...
fyfie5 Posted January 21, 2013 Share Posted January 21, 2013 hmm i would say its because of the huge tyres as i have 15" alloys and my car is slammed they are 7j et30 and 215/45/15 tyres Quote Link to comment Share on other sites More sharing options...
hickster Posted January 22, 2013 Share Posted January 22, 2013 Basically you need some spacers if you want to run those tyres- hold on here comes the maths, and I've only had one cup of tea this morning A 6j rim is 150mm (for the purpose of this calculation- shsssh) so the distance from the rear rim to the mounting face is-150/2= 75 + 45(stock offset)= 120mmYour 7j rim is 175/2= 87.5 +35= 122.5. Doesn't seem too far off, so a 5mm spacer might sort it or go to 195/50/R15 tyres which will also save you a lot of money in fuel. Quote Link to comment Share on other sites More sharing options...
vtec2011 Posted January 23, 2013 Author Share Posted January 23, 2013 Cheers lads.. I want to get smaller tyres but the money isn't there for the moment So I might get 5mm spacers from Halfords which only cost 10 quid for two.. A bit too cheap but its only for part time until I get a set of decent tyres Quote Link to comment Share on other sites More sharing options...

hickster Posted January 23, 2013 Share Posted January 23, 2013 Worth a try- remember you'll be 5mm closer to the outer arch.For anyone using that calc offset is measured from the centreline of the wheel and we're dealing with positive offsets which is why it's added.[Disclaimer- all measurements and calculations are approximate and may not contain any accuracy whatsoever!] Quote Link to comment Share on other sites More sharing options...
vtec2011 Posted January 23, 2013 Author Share Posted January 23, 2013 Cool thanks for the input. As for my Civic not been lowered, it shouldn't be much of a problem when the wheels poke out more. Problem is when I put the alloys back on with those tyres, its going to effect the speed and fuel economy. I noticed a huge difference when I fitted the original steelies with 175/60/14 tyres on, felt soo much better! Quote Link to comment Share on other sites More sharing options...
