Do I need to replace this tire?

So, I'm at about 5600 miles on my 900 Custom, and my rear tire is pretty much shot. It's not down to the wear bars yet but there is very very little tread left down the center. What I'm wondering is if my front needs replacing too. According to the SM the limit on the front is 1mm but as you can see there is some cracking, and while I may have more than 1mm left it's not much more. Wondering if I should just go ahead and do both while I'm at it. Here are some pics using the old penny test:







Here's one of the rear:


Gotta say I'm not the least bit impressed with these tires. I've heard of V2K owners getting better life than this. I run the front at 40-41 and the rear at 36-38, and I only weigh 150lbs. Has anyone else done this poorly with the stock tires?

I always replace both tires when the back one wears out. Doing so allows you to buy the same brand/type and you won't be worrying about it while riding down the highway at 80mph.

Measured mine yesterday. At the center there is 4mm of depth with 12000 km (7500 miles).

Service manual says replace rear at 2mm up to 130 km/h (80 mph) or 3mm over 80 mph. Front replace at 1mm depth.

The tread still looks fair to me on the rear....I ride them down a little further.
But the front does look worse to me. My front usually will out last my rear.
Your front seems to have less tread than the rear.
I would replace the tires due to the cracking or "dry rot".
You mentioned the miles.....But how long have the tires been in service (time wise) ?

I ran my rear tire to 7100 miles...but I was down to 1mm in the center of the rear tire. Didn't realize I had gotten it down that far...otherwise I would have replaced it sooner.

I went ahead and replaced the front with a Metz 90/90 at the same time...even though my stock front was OK.

Good point regarding the time. Still, it hasn't even been 2 years (will be in July). And although I don't recall the exact tire manufacture date, I did check it and it was as good as you could expect for a 2007 bike.

If I have to replace both I'm probably going to have to give up on going to the 200 rear. The $60 difference between the 180 and the 200 is already pretty ridiculous, and I don't think I can justify it if I have to layout another $95 for the front

I got 6500 out of my stock dunlaps on my 900 classic. I do think I was running low tire pressure though. My Metz replacements got 12000 rear.

I put 10,000 + on my stock rear tire before I replaced it. But by the time I did the center of the rear tire was almost smooth. The front still has plenty of tread left so I didn't replace that one. Probably should have replaced it sooner but didn't want to give up the last few remaing nice riding days last fall. Had it replaced over the winter so no lost riding time.

I got rid of the OEM 'stones as soon as the rear wore out.
Aftermarket, I replace the front for every-other rear.
On my 3rd front now... got over 22k on the Dunlop E3.

Ya I have 6200kms on my OEM's and I think they are crap. I run both at 41psi front and rear. I'm going with a wider rear as wide as I can. Time for a good burnout. lol
