Townmate T80 Tyres

Hi Guys,

I know the Townmate has 2.50 x 17" tyres as standard fitment but has anyone have or every had fitted 2.75 x 17" tyres on their scooter?

Are they OK, do they have plenty of clearance in the front fender and rear wheel arch?

The reason I ask is in Australia, the Honda CT110 has 17" rims but they run 2.75 profile tyres so they are readily available as they are the standard form of transport for Australia Post therefore there are squillions of them. So I don't think I will be able to get 2.50 profile tyres easily or at a reasonable price for that matter.

Feedback welcome.

Cheers, Frank.

Should be ok as there appears to be plenty of clearance. Will put up gearing slightly & make speedo read low if fitting one on the front also.
Maybe better to retain 2.50 x 17 on front as they dont wear out as quick.

Hi JohnW,

Thank's for sharing that.

Cheers, Frank.

Bought a set of tyres from Buster Motorcycles http://www.ebay.co.uk/itm/Honda-Motorcycle-Scooter-C50-C70-C90-Cub-C90-Tyres-Inner-Tubes-Rim-Tapes-2-50x17-/280910763360?pt=UK_Motorcycle_Parts&hash=item4167961560
Front & Rear tyres, 2 tubes & rim tapes for just under £40 including carrage. Came within 4 days good service & good price. tyres by Couger, tubes Vee rubber

Sounds a good deal John.

I picked up a set of Michelin tyres (Wets) ... Well I am based in Ireland. Did you ever see a tyre with as many hairs sticking out.

Good looking tyre looks prickly never seen one like that before.

Recently I changed tires.
On the front wheel I placed 2.5x17 in the rear 2.75X17.

The tires are the M22 by Metzerler.

Mines are Metz too,i change them 9 months ago.

My old tires were dunlop



I have not tried the new yet, as my T50 is at this condition






You are pleased with yours; all these months?

How much has the 275 x 17 tyre increased the gearing, does it make the bike less capable on hills & head wind?
Is your green bike a T80 or T50? Looks like one of those Jap home market imports that were recently advertised on eBay single seat, electric starter, 3 speed gearbox.

tidy tho what ever it is not sure about the colour , ,I have only ever seen blue ones , out of intrest how many colours did t80s come in

JohnW, When I bought it 10 years ago(this is second hand) , its licence was written that it was a regular introduction to my country from the delegation here.
It is genuine T50, with 6-volt battery and 3 speeds, without starter.
But because I've changed a cylinder with that of the T80, keeping the same connecting rod , crankshaft and of course the cylinder head, now it's T71, with a lot of compression.

About the rear tιre, when i bought it the size was 2.5/17 as the front one.
I decide to try 2.75/17 for the rear tιre, I do not know how much this affects the transmission ratio, I have to measure the tire perimeter and make calculations.
But because I usually drive with a passenger I think it helped in the sense of comfort.
Also because I brake with the rear brake, i usually use the front when I want to suddenly stop, the wider tire helps to slow down better.
I have not noticed a problem with the motorcycle control while turning, or any reduction in performance because of the greater road contact.
But I always have to take care that the tire has the right air pressure.
Overall I am very pleased about this tire selection.


barker, at my country there are only blue and green T50/80.

Thanks, yes I do now recall your previous posts stating what the bike is. Yamaha obviously made different specifications/colours for different countries. As Barker say only blue & grey in UK, but Japanese home market had green T80's (and possibly T50's)
The 275 tyre looks a good mod on your 71cc Townmate which if it still has the lower T50 gearing would bring it up to around the standard T80 (with 250 tyre) gearing. It may be a bit high for T80 gearing especially in hilly country.

I have seen Yellow examples in Greece but from what I have noticed, more T50s than T80s.

Presumably due to taxation I would think a 49cc T50 would be classed as a moped where as a 79cc T80 a motorcycle. No doubt 'duckrider' can fill us in on that

Yes, in my country, motorcycles with a power of less than 50 cubic centimeters are considered to be mopeds and have more favorable conditions for payment of traffic.
Until 3 years ago, raising a driving license was a very simple procedure and could be done for people from 16 years of age, so many bought it as a T50.

I do not know how many colors the T50 / 80 is produced, but I think the yellow must have been a custom paint.
Like the chrome plating I've done.
