Well here I am again buying new sneakers for my 1988 R100RS for the first time. She's currently wearing her original shoes and while they've got plenty of tread depth left, they're way too old for actual riding.

After a little internet searching, I'm back here looking for some advice. I want a durable, predictable tire with good looks that cooks and cleans. Any tips?

Michelin Pilot Activ is my

Michelin Pilot Activ is my H-rated twin-shock solution that meets all of your criteria, but it's a bit more expensive in monoshock sizes, and the rear may only be available in a V-rated (stickier, maybe not as long-wearing?) edition in the correct size. But I'd probably settle for a Shinko before going past the end of the driveway on 30yr.-old OE tires.

It appears that the Pilot

It appears that the Pilot Activ doesn't come in that rear size. I was going to suggest it...I'm running it on both ends of my /7 and like the tires...but didn't see the proper sizes.

Metzeler's

I ended up going with the Metzeler Lazertec's F/R. I'm not a fan of the look, but the reviews were favorable and they're one of just a small handful of options for this bike. I'll report back in a thousand miles with a review.

The local tire shop offered the set installed at $400, all the big websites had them at $200 shipped. Looks like I'll be installing them myself.

OP has apparently made his

OP has apparently made his tire choice, but Competition Accessories and BikeBandit both show the Pilot Activ rear available in 120/90-18 in V-rated for about $120. BikeBandit shows an H-rated tire in that size as presently back-ordered, but perhaps unusually, shows the H-rated tire priced higher than the V-rated.

We'll see how these

We'll see how these Metzeler's hold up and perhaps I'll try the Pilot Activ's out next go round. I've run Michelin Pilot Power DTC's on my K1200R for a decade and have nothing but good things to say about their performance.

The Metzeler's were waiting at the back door when I got home after work and being the sensibly impatient guy that I am, I decided to head straight over to the garage to get them installed. First time pulling the wheels on the RS went pretty well. Didn't even need to lift the bike it's so perfectly balanced. The other day I was stopped for ice cream with the little lady and noticed that both wheels were about an inch off the ground on center stand. She usually just kisses the ground with her front tire but with some gear in the bags she's perfectly balanced.

I've mounted all the tires on my old beamers etc but this was the first time mounting up modern tubeless radials. Breaking the bead turned out to be the most challenging aspect initially. I usually just force the bead off with my bare hands but this was clearly not going to work. I enlisted the help of a 2500lb C-clamp that I use to adjust rocker end clearance and they finally gave in. Mounting sans tubes was pleasant although the tires themselves were a bit more challenging with the heftier beads. I found using 4 trigger type clamps put the final beads in place with relative ease.

The worst part was having to remove the rear left luggage carrier in order to remove the rear wheel.

Put 125 miles on the new

Put 125 miles on the new Metzeler Lazertec's on Saturday with the future Mrs. Slash2 on the back and boy did they change the road handling of my RS! I took it relatively easy for the first 20 or so miles, scuffing in the new rubber and then slowly pushed the bike further as the miles ticked by. We did a good mixture of tarmac, dirt, grass, gravel, bumpy railroad crossings and a few hairpins. The tires performed quite nicely on all the above surfaces. They held the dirt just as good as you could ask and only gave me a few jitters in the particularly large, loose and deep gravel surfaces. I came into one turn with a tad more speed than the gravel piled up there would tolerate and while the front end gave a few inches or so, a steady throttle pulled me through the turn without incident.

We explored the Mahoning Creek Lake area in Rural Valley Pennsylvania which is about 45 miles from my home. The road along the creek is about as picturesque as you could imagine. Beautifully cut barnstone foundations could be seen under moss cover hiding in the forest as a reminder of a time gone by.

With only 125 miles on the new rubber, my review is just an initial assessment and I'll revisit this thread with a follow up at season's end.

I mentioned using clamps in my last post. It removes a ton of the resistance at the lever for installation etc and is worth trying if you do this yourself and don't have the real deal equipment.

Both tires installed, ready to go.

And the future Mrs. posing proudly in front of the RS.

NEXT UP! Got a new K36 coming in to replace the 100/90-18 that the PO installed on my new to me R69US. He's got a Lazertec up front in 100/90-18 and there is absolutely zero clearance on the drive side of the front fender and it actually rubs lightly when pushing it around the garage with the wheel turned. I love the feel of my /2 with 3.50 front/rear but am currently running a 4.0-18 K36 in the back as per the manual. Anyone run a 3.5 on the back of their R69S?

Use of the 3.50 on the rear

Use of the 3.50 on the rear depends on which final drive you have. I have the taller ratio so according to BMW, the 4.00 is warranted. The shorter ratio should be fine with the 3.50 rear tire.

Heidenau

I have been using Heidenau tires for a few years.
They are great vintage racing tires. I use them in all my bikes even the GS and the Goldie.
