Kumho tires cracking on the inner sidewall
Hi I have vossen cv3 with Kumho ecsta 245/30/22 front and 295/25/22 rear they are only 6 months old and the front tire inner sidewalks are cracking. Has anyone else had a issue like this? Thanks

If you are referring to Kumho Ecsta ASX KU21, then this is a common issue with the 22" tires thus why they were discontinued, I had the same issue and had them replaced (Nitto NT555) under Discount Tire great road hazard plan for $25 a tire. Also you should check the date when they were made to see if they are past the shelf life, I would remove them ASAP due to the danger (disintegrating) they poses for you and others on the road.

Same with other tires especially when the required load index is ignored. 92Y is def. not the right one for a heavy LS600 as often published here at CL.
Check the camber and monitor the tire pressure frequently. There are nice VIP videos with such wheels but after 1000 miles owners change the set silently. I just bought #13. Good news: They are worn before dirty

Ok I appreciate the feedback looks like I will be ordering new front tires tonight. I was thinking of putting a 255 or 265 on the front to give me a little more rubber. I'm not planning on dropping it and the 245 don't rub at all what do y'all think?

You know I have plenty of experience with this. Actually ran the 245/30/22 on my 600hL which was pushing it, but never had a problem other than the stretched look that I didn't like. I also ran those with 40psi. Now I have 255/30/22 and they are holding up fine. 265 is ideal but with my staggered setup on awd..I have to keep front 255 and rear 305 for best overall diameter match and acceptable load ratings. .no issues at all

Yes, I know. There is a reason why tire manufacturers specify the maximum load and the allowed rim size. I don't think that all tire damages are visible and they crack because of load only but to be on the secure side I would not like to be at risk and run them outside spec especially at 160mph. Often at this speed I damaged my 22's on the LS430. For smoother ride and regular wear I run 36 psi.

I ordered the same tires in a 255. I didn't want mismatching tires because the rear tires are fine. maybe it was the load index issue and I was only running 38psi. I got 2 new tires off eBay 206.00 shipped for both so it was hard to pass up for now. Hopefully nothing is wrong with them but they have a 14 day return policy. Will have them inspected before install. Off subject but what do you guys recommend for keeping my cv3's clean is there like a wax or sealant I can use? Thanks for the feedback guys
