But the 1500 has a smaller rear tire width than the 1800. By my math, I should be running a 175/60-16 on it. Is this true, anyone? What size tire do you run on the 1500 (I have an '88). Or will the 195mm fit without modifications? I want this to be the case, as I can mount the best run flat on the market if so. If not, and I'm limited to the 175mm, I'll just be stuck with a low-rolling resistance tire, oh darn.

20 years on bikes (I'm 27), and it's time I learn how to handle my machine. What better way than completely changing everything I know about handling! :-)
Thanks to all, let me know which sizes work for you.
If you had read this entire thread you would have seen where several of us have fit 195-55-16 tires to our 1500's . While a 60 series tire maybe closer to stock height those of us that pull heavy trailers choose the shorter tire to help with roll on acceleration when passing. I have fit the Austone Taxi tire (175r16) and liked it very much. The taller 175R16 acts like an overdrive dropping rpm about 250-300 at any given speed. Makes for sluggish acceleration.

Oh, I read it, but I keep reading on other forums that 195 is too wide.
I get a discount on car tires, I'm opting for a Bridgestone DriveGuard in 195/55-16 (this is the stock Mini Cooper size). I am adding my TPMS kit to it.
I will update when I get it mounted, as to the clearance. If it rubs, 175/65-16 Ecopia Plus is the winner. Thanks, especially for the pictures. I'll get this under way soon.

Too wide as in rubbing on the inner fender. Simply readjust or trim. I didn't need to trim for the Austone.

Oh, the plastic thing? Trim away--box cutter your time has come! I was thinking the frame--I was about to go outside with a tape measure.

This is excellent. Thanks.

Reminder, the tire needs to be installed on the rim and inflated to get the true width measurement.

I deal with these tires daily, I have measured their width. I was going to measure the available space at the back of the bike.

Where do y'all get the valve stems? There's nice metal 90° stems on the rim now I'm quite fond of.

And I'm going to go with Dyna Beads and see how they work for me.

GoldWingRev...I put a 195/55-16 on the back of my 1990 Goldwing....it's as stock as it gets, no mods at all.

It fit just fine, doesn't rub even when I load it down or run low air in the shocks. Altho, I gotta admit, when I
first bought it, I was certain that thing wouldn't fit....it looked HUGE.....but it fit just fine...

Hope that helps...

You're all set.
The majority of Wing riders that do this option do both you mentioned.

The stock E3 on the rear now is just a hair shy of 1/2 an inch from the right swing arm. I measured be tire on my car (also a 195, albeit in 15") and it's roughly the same width...you're sure it doesn't rub? How close is the bulge-y end of the tire to rubbing?

Now I sound like tk2-425 (sounds like a Star Wars droid btw :-)). The damn thing looks like it'll never fit.

I don't know about any other tire but the Austone.
Austone's right side to Wing swing arm clearance is about 3/16", left is a little more.
I'm not going out to measure, little too sick right now to move.

I think the 3/16" is about right...I ordered mine online, and was bumming when it got here.....but it actually
fit and has never rubbed....

Question Gentleman (sorry if that term is incorrect, but my momma raised me to be polite, :lol: )

When using a radial rear auto tire, such as the Michelin Alpin, on the rear of a GL1800, and a battleax on the front, are you using a bias battleax, or a radial battleax? Thanks.

I'd have to go check for sure,but I think it's a Bias ply.Either way it doesn't matter.No problem mixing and matching.
If I'da known it would last this long,I'da taken better care of it.

Doesn't the 1800 come with radials now? I'm almost positive the new ones do.

my front is a bias, as it is a traditional rear tire for a motorcycle...

Yes the 1800 comes with Radial tires.Mine has a radial CT on the rear and a BT45(pretty sure it's bias) on the front.

BTW I hated the E3 Radials that it came with.Loved the E3 Bias on my 1200 and 1500,but hated the radial E3's.

I suppose by now the original poster has heard everything he ever wanted to know about car tires on motorcycles.
Before I got my Goldwing, I rode a Honda Shadow. It had a 15" rear wheel. I had to shave down a 15" car tire to get it to fit.
There was definitely a difference in the ride, at low speed. There were days I'd jump on and take off and I'd totally forget I had a car tire out back. I could still drag the pegs and, on a few occasions, I tried to make the rear tire break loose in a turn. I couldn't do it.
I put about 6,000 miles on that tire before I got my 1500. I am planning on putting a car tire on before next spring.
I think a persons riding style should be assessed before going to the darkside.
I like long distance touring but generally I'm running the speed limits and not seeing how fast I can take a curve.
Don't get me wrong, I like an occasional spirited ride. However my "spirited" ride is not the same as my sons.
He talked to me about putting a car tire on his bike. For the way he rides, which scares the heck out of me, I advised him to stick to motorcycle tires. He may go to the darkside after he mellows out some.
Car tires will work, but there is a difference, there are tradeoffs, consider how you ride and what's important to you.
Oh, it was the motorcycle dealers around here that convinced me to go with a car tire. When I'm quoted one price, then arrive and get a higher price, I tend to walk out.

Regardless of the barage of: you must have a deathwish replies I darksided my GL 1800 with a runflat cartire. :shock: The positives by far outweighed any minor negative handling issues.

I would like to darkside my 1100 but I am not sure of what would work with the limited tire clearance and all. Anyone know???

There are no auto tires that anyone has ever found that work on the GL1100. The main issue is the very limited clearance width-wise between the swingarm.

I have a CT on my 1800 and it has made a difference. Got tired of putting tires on front and back, front mainly due to scallopping. if you travel a lot you will find it to be a good addition to the bike. Put it on in Northern Ontario in July, the shop had never heard of doing this so there was no issue, also put in 3 1/2 ounces of CounterAct beads. After riding back to Victoria through Sturgis, I was extremely comfortable with the CT. My riding friends here were skeptical, but after having them follow me on a ride up to Hurricane Ridge through the twisties and not being able to find fault with cornering, they have changed their tune regarding CTs. I'm not able to drag any hard parts as I also upgraded the suspension to the 'Full Monty Traxion (highly recommended upgrade). Another plus is that after some 8K kms, there is no scalloping of the front tire so it should last considerably longer.

Read an article where the author had no axe to grind per say, and he stated that eventually the CT industry will see this as a new business opportunity.

Going to investigate putting a CT on my 1200.

Cheers

That would be great if the ct manufacturers realized there is market on motorcycles. They could make a tire that fit the rim perfectly and round the profile a little bit for those still sitting on the fence.
It wouldn't take the mt industry long to realize that long life in a tire is a "must have" for many of us riders.
Also finding a place to get your tire mounted would be a lot easier. :D

I have read the OP article and the author's post as well as every post in this thread... I will spend the extra money on motorcycle tires just like I spend the extra money on motorcycle helmets. I don't trust an insurance agent (i.e. salesman) whose sole purpose in life is to tell you what you want to hear so as to make you happy while he renews your policy. I would be concerned about folks on the phone saying they don't have any concerns when they are not educated on the issue nor in a policy making function of the insurance company. I would worry about what their lawyers would do after the fact or as a knee jerking reaction to an issue that pops up... Most today are not concerned about seat belts in buses. Insurance companies were not concerned in the sixties over installing or removing seat belts then in any vehicle... People before that were not concerned about smoking... The thing is, we get smarter... The bottom line seems to be that they are cheaper... Wow...
