I would not be concerned with those cracks. They are from the lugs flexing. I see you use chains and they will cause the lugs they contact to flex more than normal. I suspect that is why you are seeing the cracks so soon.

It may be OK but I don't think t's natural. The only tires I have ever seen crack are older tires that have dried out and I've been looking at tires for a lot of decades. It's not normal and does not happen to all, some or most tires tires. I have some that are 20 years old and look just fine and I have seen 40 to 50 year old tires that don't have cracks. Firestones if it matters.

It's a quality control or manufacture inadequacy of some sort and it needs to be determined what causes it to know if OK or not. Probably OK but I can't say for sure. I've never seen one with cracks go flat.

I would not be happy to see the tires cracking like that. It is not a problem now but what are they going to be in another 5 years? Tractor tires should last a long time. I've seen some tractors from the 40's and 50's with original tires.

What are the ID numbers on your tires? The last four digits will tell you the week number and year manufactured with the last two being the year. example 4012 would be 40th week of 2012.

When I bought my MX5100 with R-1 tires, they were cracked like that from new. Tractor was a left-over model from the year before and sat out for a while. Was able to get it for a pretty good price. 5 years later, they look the same, but the tractor stays in the pole barn when not used.
