Rd350: 100/90 18 vs 90/90 18 front tire

[MRDRcycle]

Hello,

I'm looking at getting a new set of tires and am wondering if there are any issues with moving to a larger 100/90 18 front tire for the rd350 73'

Good luck on finding the Avons here in the US...

agreed. bt46 is a good alternative

The 100/90 Avon on the front is a very tight fit. I put a 100/90 on the front of a '73RD and had to let the air out to get past the fender bolts. Ended up putting the 100/90 on the rear, and a 90/90 out front. Looks better too, but that's personal taste.

Thanks for all the great info! I think I'll stick with the 90/90 18 for the front.

How are you getting hooked up with Avon tires ?
Been looking for 130-70 and 110-80-18's for the Dymags on my RZ for a few years now.

Sorry for the super late reply: I found the Avons on eBay, and at a good price too! Seems 18's are low demand sizes.

Very nice rims/wheels.

Thanks for the feedback! Shouldered alloy rims are my fave

I ordered a 90/90 for my RZ and fat-fingered something. A 100/90 came in.
I'm using it anyway but if doing it again, I'd get the 100/80 in the BT46.

Wouldn't a 100/90 be just too wide for a stock RD350 rim?
Can't say I am 100% sure, but aren't the stock rims something like 1.60" and 1.85" wide?
Using wider tyres on narrow rims won't give the correct tyre shape.

You make a good point.

You end up using only 1/2 the tread available no matter how far you lean it over.
