I was forewarned. These tires began to show nasty weather cracks this year. I don't know how long they'd been there but I got under there last week and saw them. Some of the sidewall cracks are deep and yet there are cracks between the rows of treads. My advice is to dump tires that have deep weather cracks. Incidentally, my bikes are virtually never in the sun but they are in freezing weather all winter.
When the tire goes it literally falls apart as if it were made from cookie dough. By the time you get her reined to a stop the entire tread has come loose from the belts and is falling to bits. I've never seen a nail or puncture on the ones that went, nor was I doing anything tire-shredding when it happened.
All these POTHOLE CRATERS that are everywhere this year worry me. I'm shocked I haven't blown a front tire because I've hit some 3-5" deep craters dead on. You can't keep your eyes glued to the roadbed 100% of the time!
Also, I KNOW some of the Savas are fine, it's just that you don't know whether you got the tire that drunk and sloppy Boris made or the one that upstanding and hardworking Vladimir made. Country of origin is important.
INFLATION- One last thing, I prefer riding on tires that are a bit OVER INFLATED. Not crazy high but 25-30 psi cold.We do it with MOTORCYCLE TIRES all the time. I run 42-45 psi on 35-38 rated Avon Venoms with no problem, only better handling, better road feel, better milage, and faster acceleration. Is that killing my scooter tires?

Well, I doubt the "better traction" statement about over-inflation - that's precisely the problem with over-inflation, that you lose traction. But I'd be surprised if running a scooter tire 3 psi higher than rated (or even 10 psi higher) would have a substantial effect on the rubber cracking and falling apart.
Bajaj recommends 18 in the front and 25 in the rear solo, 36 in the rear with a passenger. I usually run the back tire a little higher, but no more than 30ish, 36 seems awful high.
I've had Chingshen (sp?), Zippy 3's and 1's and the stock tires on the Bajaj. The 1's were the best and the Chingshen's (look like zippy 3's) were the worst in terms of cracking. I actually rode on the Bajaj tires for about 5,000 miles. Wear and ride like iron, poor traction in wet conditions.
Some of the guys are running Pirelli. Cheap enough and sticky, but wear fast. But if you have split rims and can change tires easily they might be the way to go.

So you saw the cracks and didn't think they would be a problem? I would replace any tire that has checking before I rode it anywhere outside my neighborhood. How old are the tires? They must be pretty old. I have 4-5 year old Savas on my GS150 with sidecar and they have no checking.
I thought the Sava problem had to do with white walls that separated at the color seam - not checking.
You can find zippy 1's for that price online too. I would never run the sl26's again. Granted I used them on the track (once and only once), but after a while you can actually see little bits of rubber coming off the tire, then they got real slippery, real fast. I'm sure for most city riding the are OK, but if you were going on a very long ride, say Duluth, no way would I trust them. For the same price you get a much better tire, why risk it.

Oh, man, I'm in big trouble then. I've noticed deep checking (mostly on the sidewalls) of the big fat tubeless tires on my Malaguti too. Needless to say, the truly ancient tires on the Primavera are badly checked too (I did buy a set of really nice but yet uninstalled MICHELIN'S for that bike a while back)! I suppose it's time for a round of new tires for the house! Beats road rash.
