I've never understood what the logic is behind what is the biggest tire that will fit on my bike.....I prefer, what is the best correctly sized tire that will fit on my bike. The biggest tire is often one of the heaviest, least responsive tires.
YMMV and standing down from my rant.

Default Re: largest size tire that will fit

that is dependent on the rim size...

the OEM rim is 2.5" wide x 17" diameter...and the best size tire IS the 130/70-17...near perfect profile match to the 90/90-21 front on a 1.65" wide rim...

that said, with a wider rim on the rear...say a 3.5" wide x 17" diameter, i have fit WITHOUT swingarm modification a 140/80-17 Distanzia...i have heard that a 150 will fit with some mods to the swinarm...SamM i believe has done this...but remember he and I have both changed the front rim to wider to accommodate wider, lesser diameter tires...

putting a 140/80-17 or bigger on an OEM rim is a waste of tire profile...and a waste of $$$

larger fatter tire will put more rubber on the road and be slower to wear.

Sorry wrong, without the right rim the contact point will be narrower as the tire will be pinched on to a too narrow rim. Been there done that. Also by changing the profile of the tire you will upset the handling of the bike.

JMHO But unless you spring for a new rim and all I'd stay with the factory sized tire.

I have a 150 Distanzia. After OEM wore out at 8,000 miles, I put the Distanzia's on. Just turned over 29,525 miles today. Need to replace, down to the wear bar. Front is cupped. Great tire. 98 % road.

Mike how did you get 8,000 on the OEM?!?! Mine rear was toast at 2,500. I went with a set of 761 Kendas and they are OK other than the rear hates wet pavement. But I have a set of 606s in the garage for summer so I'll live with the Kendas,

8,000 miles... You must have REAL soft roads there!

130-80 17's work, the rim could be a bit wider but it does work.

Default Re: largest size tire that will fit

I concur with wymanwinn!

On the first version of my '08 KLR, I had Woody's Wheel Works build me a set of Superlaced 19/17" Excel wheels. That project is chronicled on this site. Do a search for Excel Wheel Project and you'll find it. I went with Woody's recommendation about wheel and tire size. What I found out was that I had to do major modifications to make that tire and wheel combo tire fit. Even after doing the mods the tire still just barely touched the chain. My rear Excel rim was 4.25" wide. In hindsight, I would not recommend the 4.25" rim on a KLR. You'd be much better off with a smaller rim. I also would not recommend the 150mm rear tire on a KLR. There just isn't enough clearance with that tire size. Sure you can make it fit and maybe not rub, but it's too wide. You'd be much better off with a 140mm rear tire. With that size tire a 3.5" or 3" wheel would be perfect. I will say that the 19"x2.5" front wheel with a 110/80-19 Anakee was awesome on the front! Anakee does make a new 140mm radial at this time. When I did my project, it was my intent to go tubeless and use radial tires. That didn't quite work out as planned. The 150 was my only option back then. If I were to do it again the new 140 on a 3.5" wheel would work just fine. The bigger contact patch makes the bike handle much better. Big difference over stock. You may not get it, so to speak, but if you ride one you won't for-get it!

At this time, I'm getting ready to send my rear wheel back to Woody to be turned into either a 17"x3" or an 18"x2.18". Haven't decided yet. The tires that I will be using is the Heidenau K60. Owners of the Heidenau K60 report better than exellent mileage from these tires. I'm keen to get them on my new Lightened KLR.

Hey Sam, at the risk of hi-jacking this post, let me know how you like the Heidenau tires. I have a pair in the basement waiting to be put on as soon as the old ones wear out...

Jon,
Same here. I need to finish off a set of 606 tires first. My bike isn't done yet, so you may find out how good they are before me. Let me know!

Sam when you get the back wheel built.Make sure you go with the 18.The 17 rim is cr^p for off road.

Hey Peter,
Not sure yet. I already have a rear 140/80-17 Heidenau K60 tire. It could go on my other project though.

Sorry for the hijack guys!

Actual milage was something like 7,800 and some change. I really don't know why I ended up with that much milage. Tire pressure (back) was 34 psi, front was 32. I commute 70 miles round trip, two lane road, keep it at 60 - 63 mph. I will say I wore them down closely. I didn't measure them with a micrometer, but hardly any tread was left. I won't do that again....

If you go for a Heindenau K60 , go for the 140/17 on the rear as I had both a 130 and a 140 (which I also use on the GS1100),
Why? the 130 lasted only around 5000km, I average 12-14000km with the 140, the tread blocks are wider on the 140...so that realy answers why we would put a 140 on the rear of a KLR....

Default Re: largest size tire that will fit

Thanks Ozrob! Good advice and that's exactly what I plan to do. However, since I'm going to the 21/18" wheels for the Lightened KLR, I'll be using the 140/80-18 K60 instead of the 140/80-17 K60 rear tire. I've already purchased a 140/17 K60 but it's going on my other KLR project bike on a stock wheel.

I hope the 140/18 will fit on a 2.18"x18" rear rim? Any idea if that will work? I'd like to be able to swap back and forth from the K60 to the Dunlop 606 tires fairly easily. The 606s are just too much for day in day out use. I have a feeling that once I actually try the K60 on the bike, I'll never want to swap them off. How does the front 21" K60 work?

Thanks!

Hi SamM,
The K60's on the front are quite good, I ran them on the front of the GS for a while and they hang on quite good, they corner just as well as a Tourance, can't falt them at all.
No tyre will perform in all conditions, however they are as good as anything you will be able to make it do on a heavy KLR.
The K60's are a good combination for the KLR as it allows you to commute on the black stuff, and also do off road work, as well as extended touring with out having to worry about changing tyres.
If you do a tubeless conversion ( do a search for tubeless tyres thread) the K60 is technically a tubeless tyre....so fixing flats is no problem.
Not sure about the 140 on your rim width
Cheers
Ozrob
