SPGTi 2 Posted November 17, 2006 Anyone used the above sized tyres ? It is for my road rally car and they are a gravel/tarmac hybrid tyre and only come in this size or 185/65/14. Ride height is std (maybe slightly higher), I am not averse to trimming body work and I have coilovers up front so maybe a bit more room than with fixed pan suspension. Any idea how much the size differs(621mm diameter) from 185/55/15 knobblies (these are bigger than 185/55/15 road tyres). Steve Share this post Link to post Share on other sites
Craigb 2 Posted November 17, 2006 What tyre are they Steve IIRC I tried this size in a colway and they just rubbed on the inner arch all the time. I'll try and have a look what size they were . Share this post Link to post Share on other sites
SPGTi 2 Posted November 17, 2006 I am looking at some Dunlop A2's. spec is diameter 621mm, width227mm. They are an e marked gravel/tarmac tyre specificaly designed for single venues. Thought they would be ideal for road rallies. I am struggling to get some A021s at the right price. I don't like knobblies so thought these would be better than std road tyres which I normally use.

Craigb 2 Posted November 17, 2006 (edited) Just checked and they were 185 65 15 with a heavy sidewall reinforcement I think it was the sidewall that was the issue, so scrub any of my comments Edited November 17, 2006 by Craigb Share this post Link to post Share on other sites
SPGTi 2 Posted November 17, 2006 When it stops raining I will go to the "wheel store" and measure my knobblies. If they are close I will maybe go for them. Steve Share this post Link to post Share on other sites

Steve 185/55/15 = 580(ish) diameter (IIRC), but with knobblies on, i'd add about 10mm extra to that so say 590mm 185/65/14 = 600mm Faraz Edited November 18, 2006 by Faz85 Share this post Link to post Share on other sites
