What tires should I replace mine with

[Jallen]

I own a 1982 Suzuki Gs450L, I'm trying to replace my wore out tires but cannot find them anywhere. The front tire is an Irc 3.60-r19, and the rear tire is an Irc 4.60-r16. Does anyone know what size tires would be a suitable replacement. Thank you in advance.

Hi, here is a link to a chart showing the modern size designations.

Seems to me like your best choices for front would be a 100/90-19, and the back a 130/90-16. Those you'll find are very common sizes, lots of brand choices.

Measure carefully before you put the 100/90 on the front. I tried that on the 450 we had here for a while and it was TIGHT. I think I ended up grinding down the bolt heads on the fender bolts to get just a smidge more room.

So what size would you recommend? I'm in the same boat with my 82 GS450L

You should use a 90/90/19 for the front I'm guessing 120/90/16 rear 130 may be too wide??
120/90=MR90=4.50/4.75
130/90=5.00/5.10

Yeah, the 130/90 would be way too wide.

There aren't a lot of choices in 120/90-16, but this is the same size my wife's Honda uses. Someone crammed a 130 on there before we bought it, and it was far too wide and made the bike handle oddly. It also had a much wider flat spot as it wore down.

The choices we found in 120/90-16 are the Cheng Shin HiMax, Continental TKH24, IRC Durotour RS-310, and Kenda K-657 Sport Challenger. All are good choices (even the cheapest modern tire is far better than anything available in the early '80s). I'd lean toward the Cheng Shin HiMax, personally.

If you're having a shop install the tires, they will likely insist on ordering them, but at least this will give you an idea what to order and how much you're getting ripped off.

Their web site is an eyesore, but Tires Unlimited is a real live tire warehouse in Dayton, OH. They have just about everything they sell in stock and ready to ship the same day at excellent prices, and you can call and talk to an actual human being if you want. Most of the internet tire places are just some slug in his Mom's basement with a catalog.
