So what is the general opinion on tyres for a 31k Hybrid? what speed ratings are you guys using and what tyres?? I assume 110/70 front and 150/60 rears? I want to order a set ready for when I get home, maybe the NK fairy will have delivered my yokes..... He said they'd be ready but who knows, especially as he's now away for 10 days.

I messed around a bit with tyre sizes and found that 110/70 front and 140/70 worked best for me. I keep the 150 tyre for impressing the ladies  They work ok..  |

Thanks, 140, so that might make the messing around with sprocket carriers on my GK76 rear wheel a bit easier. What brand are you using, I'm assuming the speed ratings aren't so important but I guess they need to warm up and not be too hard. RGV suitable I guess makes sense.

I think the tyres are not that special just road tyres, They are Bridgestone S20's i think they are H rated but i will have to check. They were recommended by a bike tyre man.

As Tobyjugs mentions, it’s not just the size that matters, but also the compound.
I really liked the look of the Pirelli dragon supercorsa, but was persuaded by my local tyre guy I might not be able to put enough heat into them to make them work on a lightweight LC hybrid.
I’m probably going 160 on my latest LC hybrid for the ‘look’; but considering 150 on the same size rim (4.5”) on my YPVS hybrid.

thanks, i did wonder about getting heat into them, something rated at 150mph isn't going to be much good on a 350.

Some of the small 400 cc bikes used 160 size tyres as standard. If you know a good tyre man, explain the bike and uses of the bike to him. His opinion will be very important.

Not quite the same i know but i run mito wheels on my tdr. The tdr is a bit heavier than a 125 but i run diabl rosso 3 tyres at mito pressures and they are great. Get nic and warm and have been good through winter too. Theyre h rated. Mine are scrubs off ebay so cheap too.

Choose the size witch goes the size of the rim. Otherwise the shape of the tire is wrong.

I put some Pirelli Corsa Rosso Diablos on my 'lil Mito 125 (33bhp one!). Sticky doesn't describe them. Like riding on super glue, the lean angle was intense. Pricy though and they don't last long. Never used them in the wet so can't vouch for them in those conditions.

Something with a sport compound and designed for 250-400cc bikes
No use going to the effort of building a hybrid then sticking 125 commuter tyres on it or a big bike router tyre.
Like tobyjugs I now run 110 and 140
The 150 looked nice but turn in was difficult
Using Bridgestone BT 090

Jon Hi Jon It's a 140/70 17 on a 4 inch rim It's not stretched so would go on a 4.5 rim fine Steve |

140 seems to be the consensus so I'm happy with that, no point having the thing handle like a pig..

Choose the size witch goes the size of the rim. Otherwise the shape of the tire is wrong. I agree with this. As far as I’m aware as standard a 4” rim is usually fitted with a 140 tyre, while a 4.5” rim is fitted with a 150. This may explain Steve going down to the recommended tyre for his rim. Also the rims have to be paired front and back. A wider rear usually has a wider front so the profile of the front and back radius are matching. Fitting a rear much wider than the front will result in strange cornering. Jon |

Thanks Jon, I am using GSXR400 front and rear, so I was going on the sizes recomended for that, the 400 uses a 160 rear which i know is too big for the RGV arm, but I'm fine with a 140.

Jon Before I dropped to the 4 inch/140 I was running an rgv 4.5 rim with the 150 My problem was that while on the power it did not want to turn in. You had to back off to neutral throttle, drop it in then go back on the power. I was using super sticky Dunlop GPR 70's 110/150 As per rgv) Then changed to the bandit wheel with 140 rear 110 front Bridgestone BT 090's First time out I nearly threw it on its side The other thing making a difference is the 140/70 Is 8mm bigger in diameter and is more egg shaped which is most likely helping Steve |

As long as they are H rated they are all pretty good. I run BT090's where I have an 18" rear, Dunlop Alpha 13's or Sportmax2 in the absence of Qualifier2. Summer is OK for V rated Super corsa SC0 on the front SC1 on the rear. on a 4" rim you need 140 profile On 4.5" rear rim you need a 150 profile. The 160 needs a 5" rim to allow all the tyre to be used but will fit on a 4.5" rim. Looks super butch but you get chicken strips. Front on a 3" rim needs to be 110/70. 120/60 or 120/70 needs 3.5" rim. Others use Conti attacks (super motard fave) to good effect.

I'm running GSXR 400 rims front and back with 120 front & 150 back, with standard GSXR 400 forks and a modified GSXR 400 swingarm in a 4L1 frame - the bike handles really well, when building the bike i was concerned that the handling would not be sharp enough but it turns in really well and still feels nimble,
150 is more or less the max size in a 4L1 / 4L0 frame but your 31K frame is a bit wider and i think a 160 is possible.
The advice above from the others regarding keeping the right size tyre on the right size rim is the key along with keeping a matching pair.

Built 3 hybrids in the last 4 years all running 160 rear.Looks great,no chicken strips and no handling/turning in problems,providing suspension set-up correct!
Close fit though👍
