Title: Rear tyre ratio
Post by: Notty on Monday, 16 October 2023, 02:02 AM
what is the performance etc difference  between 190/50 – R17 and a 190/55 – R17 - I notice some of you guys make that choice. Reason I ask as dealer has a good deal on 190/55 – R17 - asking for a friend  :rofl2:

Your feet will never touch the ground with a 55.

You beat me to it Irish !!

I run a 55 and like it, I'd say I find the steering a little sharper.

I've done the 55 and 180/55 thing but back to the standard. Whatever suit you I suppose, same with brand.

Same for me.

I prefer the bike on the 190/50. The others make it feel unbalanced to me, as if the rear wants to turn better than the front if that makes sense. Plus the 190/55 looks like a tractor tyre on them.

I've tried most of the 55 options all you get is a bit more steep tip in. I have had lifting kit under mine for probably 15 years so I'm used to the feel. I go on cost these days. Last set was 120/70 front and 180/55 rear PRC6 $450 ride in ride out. Around 7000km's on them and starting to feel the effects. Edge grip hasn't suffered at all. New set soon. Most of my riding lately has been commuting 80+km round trip each day, so 400km's per week roughly. So I will consult my tyre guy about a better option, Dave Oliver at Oliver's MC Tyres located at Clontarf.

I use a 55 rear and I didn't notice any difference in ride/seat height but I do have long legs.  I don't really feel any difference in turn in either.

Chris, I'm about 80% commuting about 104km averaging 3 days per week. Currently on the Bridgestone BT031's, done about 5or 6000kms i reckon, no complaints so far, no where near worn out, and still very symmetrical

I dont comment on tyres, ill just say last Angel GT i had, original type, 15th k front, 22 rear. Quite amazing i thought. Same on again now. Front was out of shape, rear just got worn out. 36 psi front, 38 rear. No tracking, no slipping, couldnt fault. Tyres b4 them were Michy 4 from memory, tracked badly was only fault. Both lasted 10 th ks.

Totally agree about "Michy" 4's tracking..
My bike had them on when I bought her..
Still very happy with the Avon Storms...
