190/55 rear tyre size

solamanda · May 16, 2011

Does the 190/55 tyre sit less wide on the rim than a 190/50? Does the extra height affect how close it sits to the chain?

I'm looking for a tyre that gives more chain clearance than the 190/50 and slightly reluctant to get the 180/55 due to having had grip issues before with the thinner tyre. Thanks

I can't offer you any empirical evidence, only a quote from Avon's online data for their VP2 Supersport series (I only chose Avon because they're one of the few manufacturers to post such data):

190/50 width=192mm
190/55 width=180mm

Not sure that makes sense, but there it is.

tyre manufacturers are allowed a tolerance on sizes and iirc its 10mm on the width.

i found that 190/50 michelins rub the chain but avons and pirrellis dont

If you go to a garage that sells tyres and put two or three together ,you will see that every tire has a different profile ,the more sport orientated the tyre the more of tighter angle while a touring tyre has a more smoother curve and less agrresive even though they are the same size so it all depends on what you want a tyre for ...what grip issues did you have with the smaller tyre, i use the 180s and the only time its gave me any stick is when i didn't give it a couple of laps warm up, on the road again only time was in the wet when i got a bit carried away on an overtake. I always think its down to choice of tyre ie model/make and wot you use them for .full lean 180 no chicken strips yes please...
