I have a spare set of standard wheels for my RD350lc and I was thinking of putting bigger tyres on them. I have 90/90 and 110/80 BT45's on the bike at the moment. What bigger sizes has anyone fitted on the standard rims. I was thinking 100/90 or 110/80 avon roadriders on the front and 130/80 on the back. Cheers. Rick.

Hi Ozzie, when you say you run those sizes on your 250 what sizes exactly?

I think I will stick with running tubes, thanks for the input. Still fancy slightly bigger tyres than standard. Still fancy going a bit bigger than standard on the tyres, 110 on the back looks too skinny.

Don't think the problem is losing air but tubeless wheels have a different lip on them on the inside to stop the tyre coming off the rimm under load or if deflated.
Certainly would not risk it.
What benefit is there?

Back in the day I worked in a Yamaha main dealer . Mitsui staff told us as a fact that LC alloys can be porous so cannot be used without tubes .
As for tyre sizes , I can only say again that mine handles so much better on standard sizes .
All that over sized tyre has to go somewhere - when it cant go sideways it goes upwards .

.... LC & YPVS standard size tyres do look skinny, but it doesn't matter, as long as you have good ones fitted they will work well.
They are 25 / 30 year old machines after all..

Sounds like it is definitely tubes then, and I will stick with standard sizes for now. Cheers.

My 4LO has slightly larger tires and the bike doesn't sit on the centre stand properly. Anything other than perfectly level ground risks a tip over. As well the larger front rubs on the fender stay which is REALLY annoying. I ended up taking an angle grinder to the edges of the tire to get it to fit properly.

I remember this being discussed years ago. might have been on another forum. Im only going on memory, which isn't the best these days.
There are a couple of different types of rim, WM and MT. WM is the tubed type and MT is Motorcycle Tubeless. LC's have MT rims, so you'd think that tubeless would be ok but the rims can be porous so you need tubes. As for sizes on an LC the standard sizes are best. Its usually possible to go up or down a size, and there are charts on the interweb that will say which size rim can take which size tyre. but i think for the 1.85 rim we have on the LC the tyres already at it maximum size.
The upshot is for standard wheels stick with the recommended size and type. LC's are old bikes, they wernt designed for modern tyres. However if you fit modern wheels then thats another thing altogether.

PS has anyone run them without inner tubes on the standard rims? Im sure Niall Mackenzie said he was running tubless tyres and no tubes on his recent restoration of his LC in CMM, I think ? |

Hi, stay with tubes for sure. and run standard size tyres, just go for top quality rubber. it will handle better.

Hi Bare, not sure if you understood my comment properly, but I was referring to the colour of the wheels not the tyre sizes ;-)

Just read in PB mag, John McGuiness rode the Paton 500 to a 110 or 115 mile an hour lap at this years classic TT...with a 110 on the rear, I think thats enough reason for me to stay at standard sizes.

Back in the day, the Michelin TG22s we used were not std sized. But on the front I think the TF was near to std size ( they weren't measured the same , ie 120/90) And I cant remember the sizing numbers, but they did not "ruin" the handling. I never got on with a Dunlop on the front, so have no idea on the sizing of them. I'm having a turf out in my old w/kshop, there may be an odd old tyre around.
