The jog has just done 8000ks and is running on a nearly slick rear tyre. The standard Cheng Shin rubber was shyt in the wet but good if the tar was hot.
Cycletreads is probably the best place to go but I want to know if anyone has fitted wider tyres to the rear of a Jog?
Standard are 90/90 front and back.
Will 100/90 fit without hitting the shock? In 10in they go to 130/70
I'm looking at Michelin S1's front and back.
Any advice from those in the know will be greatly appreciated.

Be carefull changing to wider tyres. It's not like a car. The handling of the bike may not improve.

I guess the biggest thing is what will fit width ways with out rubbing against anything. So long as it doesn't rub you should be alright.

Tyres are all about compromise. The softer the compound the greater the grip, the faster the wear. Hard compound, alot of wear but little performance. Remember: the more tyre contact with the ground = more friction (bad for speed) and more grip (good for cornering).

IMHO - go big, go to Cycletreads, buy it and do it yourself. :yes:

It appears that you can get up to a 3.5" boot on the back no probs...go for it.

Cheers for that. I think I will stay with the 90/90 considering the hight of the tyre is 90% of the width so I cant be bothered working out other tyre ratios.
The S1 tyres are ex wet race tyres so should be a way better compound than the standard but shorter lived.

As far as the big bore kit goes, its definitely in the near future plans I'm looking for more acceleration rather than top speed, no moped will outrun "Boi, I wish my nuts would drop, Racers" if they want to "play" at 3am. I'm just watching a few others with kits fitted to if I can stay away from premix but its looking like leaving the yam oil pump and pre mixing at 100 to 1 for insurance I just have to make my mind up before re jetting the carb.

Of course, the other option is the same tyre on a wider rim - that's what I've done on my Lammy and it really improved the behaviour. With a scooter you've got much more of the weight distributed to the rear wheel so a bigger contact patch is all good.

don't worry about sizes, just go get some conti twists and be done with it. They are great and I would say better than the Michellins for day to day use.

Cycletreads are normally pretty good.

the conti twists`that I had developed a split in the rubber after about 2000km on them as though the rubber was coming of the casing

So for me I will not go near them

P.s I was not the only person who had this issue

Your not the first person to mention faults forming, it seems Monday and Friday tyres are not so good even tho some have no probs at all.
Scootling are having a sale on this week and Cycletreads have a large variety so best just to fuel up and go for a ride around town.
