Rear tire size

Postby dtrider » Sun Mar 08, 2015 6:20 pm



I was looking at the various online stores for tire prices, and I noticed on CruiserCustomizing.com they state:
Your front tire is a 130/70-18 and your stock rear tire a 180/60/16. You have the option of selecting a 180/70/16 for a 10% higher profile to give you more ground clearance when cornering plus it will be a bit easier to put the bike on the centerstand. It will also correct the speedo to more accurately show your exact speed rather than overstating it.

How noticible is that "higher profile" as far as handling goes? How much does it really raise the bike? I think I'm tall enough to be able to handle it, or is it really a significant difference?

1.42" taller so height would be near 3/4" rise in rear. If 1800 reads speed from rear , at 55 mph speedo reading the bike is running 58.2 mph. If off front wheel it's not a problem.

I run a 1.75" taller tire on my GL1500 and it rides great. Engine rpm is lowered by 400.

Curious? What rear tire do you run on your 1500?

There is a slight advantage for a 70 vice the 60, in that is does help correct the speedo error. Secondly it only raises the rear a small amount, it is important to maintain is the tire width, there is little room to play with. More critical is finding a tire with the weight rating adequate for an 1800, at 897# dry that's a heap more than most scooters and we tend to add more with cargo, passenger and trailer hitch and tongue weight. If you do load up you'll notice 1st has a little less advantage but shifting to 2d is put off just a bit longer from a dead stop. I wouldn't eye it as a mpg boost, it takes more wrist to pull away from a stop and the EFI adjusts for the variant engine load and accelerator anyway, it would be a minor change at best.

I have been using the 70 series (Avons) on my wing since 2005. I like the extra clearance, my speedo is now correct, and I "may" be getting a little longer life on the tire. I don't track the tire milage because I tend to get a little cupping with the Avons and never go to the wear marks. I put up with the cupping because of the great traction in the rain.
I think the average speedo error is about 7% and the taller tire makes mine match the GPS perfecrtly.

I have been running the larger tire now for 4 years. I have not noticed any change in how the bike looks, handles or feels when riding,
It does correct the speedometer however to exactly what the gps reads and that is why I like it. I do not have ABS brakes however and I'm not sure it would be wise to change tire size if you have ABS...unless there is some way to adjust the braking system to compensate.
I should mention too I have not noticed any change in how long the tire lasts.

Tire size will not affect the operation of ABS. It is not checking the speed of one wheel against the other, it is watching individual wheels and monitoring for sudden deceleration which would indicate that that wheel has (or is in the process of) locking up.

If the tire is a Dunlop Elite 3, it is not a car tire. ., https://www.cyclegear.com/tires/dunlop- ... -rear-tire

Dunlop E-3s are motorcycle tires. They are available in Radial and Bias Ply construction. I run the E-3 radials on my 2002 GL1800 and can say the Radials are great if you have a flat 30 miles from nowhere. They are not advertised as run flat for liability reasons but I've had the occasion to test the rear radial E-3. Perhaps the previous owner had another rear wheel with a car tire on it; there are many who opt for the dark side (car tires) and that may be an advantage in Alaska.
