    CL350 tire selection help

    Sorry in advance if this ends up being long winded.

    I've done a lot of searching and ended up more confused than when I started.

    I've got a 1971 CL350 that I need tires, tubes, and rim strips for. The bike will get road use only, mostly low speed city streets, occasional highway or country road.

    Currently the bike has 3.60 by 18 rear and 3.25/3.60 by 19 front

    I also have a parts bike with 4.00 18 rear and 3.00 by 19 front

    I'm not sure which if any of these are the stock (or correct) size.

    I do like the 4.00 on the rear of the parts bike better, as far as looks go. Much beefier looking. The 3.60 looks rather wimpy in comparison.

    But that's besides the point. I'm looking for safe, inexpensive (as reasonably possible...hopefully very inexpensive) tires tubes and strips for this bike and am totally open to suggestions.

    I'd really like to know the suggested sizes and their metric equivalents.

    Thanks for any help.

    I'm so excited this project is nearly ready to ride

    The most important place to spend money is the tires.
    They are your ONLY contact to the road ... all of your stopping power, and leaning/turning/swerving abilities come from the RUBBER.

    It is THE weak link of the bike. Please please do not cheap out on tires.


    That said ... I also have a cl350... wider rear tires are important when the bike has enough power to spin out ... yours does not... so going wider than 3.5 is pure aesthetic and not functional...
    ... in the front narrower is again better as it's far less sprung weight but more importantly easier to turn.


    Stock rims are 1.6" rim with 3 inch rubber front and 1.85 inch rim with 3.5 inch rubber rear.


    Please pay attention to this chart showing the standard and safe widths of rubber to rim. A super wide rubber on a thin rim is asking for death by pothole...

    Lost_Cause beat me by 6 minutes, must have been halfway through his reply when I began!
    Good on ya for coming up with the chart.


    Are those sizes the current tires on the bikes?
    You'll want to have a look at your rims, rim width will dictate which sizes of tires you can safely mount. Mounting too narrow or too wide of a tire on any particular rim will change the cross sectional profile of the tire and it won't work the way it was designed to. I'm always referring to this chart, you can do a Google image search for "tire to rim size chart" or for narrower rims add the word "narrow" to your search for a chart with more sizes listed at the top end of the chart.

    I'm pretty sure the rims are stock. Sorry, but I'm really not quite sure what I'm looking at with that chart. It looks like there is no standard size for a 1.6 inch wide rim? Is the shaded part the safe size?

    So I could go from 2.25 to 3.60 on front or back?

    But only a 80/90 would be safe metric?

    Yes ... 1.6 is not endorsed by the DOT since the 80's. Thinner is better performance wise but stopping power is diminished when the front wheel has that small of a contact patch.

    Your front is a 1.6 ... your rear is a 1.85 (assuming stock)

    The shaded areas are considered safe. People on here say one or two outside safe is also okay. I disagree but I ride to the limit.

    I have 2.15 inch rims on my front and rear. I have found 4.5 actual rear and 2.75 actual front is the best handling. My bike is highly modified though... way more power

    Old pic but gives a good idea how wide a 4-inch nominal (4.45 actual) is on a bike of this size.

    Nice bike Lost Cause. That's a great look!

    Would you agree with longdistance rider that my best bet is 3.00 19 front 3.50 18 rear?

    Or should I be measuring my rims?

    Are there common metric equivalents?
