I'm sure this has been done to death, but can anyone confirm the correct tyre sizes for a 350LC please? I have found conflicting recommendations, both on-line and in person, but want to avoid buying the wrong sizes.
I will be fitting Roadrider IIs and assume sizes should be
Front 90/90 x 18
Rear 110/80 x 18
TIA
Stu

Yep, I believe you are correct or 3.00 18 front/ 3.50 18 rear old money.
Properly skinny either way when I look at my hybrid with 120 front and 160 rear!

Yes sizes are correct, be careful of the speed rating though, over S rating will take a long time to heat up and get sticky, personally I use a P rated tyre on my LC out of choice, only rated to 97Mph, but I don't do those speeds these days, and after all 97Mph would show around 106Mph, just something to think about, no point having a V rated tyre IMO.
I am not telling you to use P rated tyres, just giving you some info

Something that doesn't even enter lots of peoples minds, a problem more akin to the hybrid with fat tyres, but still an issue with some smaller tyres. AM22 is I think V rated, but a soft compound race tyre, very expensive too, they have a good reputation on track or road, haven't tried them myself as can't justify the cost. And there you go with the issue of tyre choices, not normally given enough thought. |

I've got Conti Race Attack 2 on mine.. Soft Front & Medium rear. While I’m sure I’ll be using a 160 rear, I’m in two minds whether to use a 110 or 120 front. Have the choice of 2.75 or 3.5 front wheels also. Jon |

I think the 110 front/160 rear profiles are too far apart and the front could lose grip easily and tip in too easily. I'm no racer or tyre technician, just my 2p worth. |

Oh and the front brakes on my hybrid are extremely good, so the contact patch is vital to be sure it doesn't just lock up. The HEL master cylinder is adjustable to a degree and the modulation I find excellent. You get what you pay for here.

I prevaricated for a while over this as there is talk on here about using slightly larger sizes.
In the end I put standard size Avon Roadrider 2 on my standard LC2 and I’ve got to say I’m really pleased with them.
They are V rated for no other reason than that what was available at the time.
One tip: Choose your fitter carefully. Not all places can balance the front wheel on their balancing machine as the front wheel spindle is apparently super skinny - the rear is fine. It’s not hard to do it manually if needs be.

I know everyone goes for skinny tyres nowadays for better handling but come off it we're not going to actually scrape are knees round every corner ( tried it for years but could never do it)... everyone fitted bigger tyres.... skinny tyres just don't do it for me?... anyone recommend bigger sizes?

Most people fit the right size tyres for the rim. I don't know anyone who thinks skinny tyres make for better handling. I know a few who think the opposite. Some people fit big tyres because they think it looks good but fitting tyres based on how good you THINK they look is not something most grown ups would do. The fact is that bikes designed to be fitted with skinnier tyres tend to handle better. A Moto3 bike will corner faster than a MotoGP bike. The wider tyre is needed for the power and weight of the bike not the handling. |

I fitted a one size bigger front Avon to the lc2 wheel in my yellow Lc. It just rubs on the mounting bolts for the mudguard !
Took it off and fitted a standard sized tyre. I read up a lot on oversized tyres on Lc and Pv wheels. Majority view was stay standard with sizes.

I read up a lot on oversized tyres on Lc and Pv wheels. Majority view was stay standard with sizes. Dusty🙂 If you fit a tyre too big for the rim it's just squeezed in and ends up pointed in the middle. That will make the bike taller either at the front or rear. My mate fitted a 125 to the back of an LC and it looked ridiculous, like a big balloon. The YPVS rims are a bit wider so there's a bit more wiggle room. We all pretty much fitted a 130 KR164 to the back of our YPVS for proddy but it seemed everyone just copied everyone else. The rear Dunlop would rub the chain guard unless something was modified to prevent it. Modifying anything to allow the fitment of a larger tyre was against the rules. That meant everyone who ran those tyres was riding a bike that wasn't compliant, basically cheating. I guess that technically allowing it to rub a notch out of the guard would actually be legal? Mine had a piece cut out of the chain guard to give clearance but a scrutineer once failed it for that. I put some tape over the cut-out and he passed it  |
