In owners' own words
Verbatim excerpts from complaints filed with NHTSA about Lionhart. Reports are published by NHTSA as filed and are lightly cleaned here only to remove intake codes.
Truck started shaking like a tire was out of round. Right front tire had separation (several large bubbles on the inside of the tire). I replaced that tire with a spare of a different brand. About 2 weeks later the left rear tire had the same issue. These tires are less than 1 year old and have less then 15,000 miles. I do not trust these tires any more and replaced them at significant cost.
The contact owns a 1994 Chevrolet Suburban equipped with two Lionhart Tires, Tire Line: LHS, Tire Size: 305/30/ZR26, DOT Number: TB2ACY50. The contact stated that he had installed two Lionhart tires on the front of the vehicle. The contact stated that the vehicle was a secondary vehicle that was not driven often. The contact stated that he observed a bulge on the tire, and the tire sidewall was separating from the tread next to the bulge. The dealer was not contacted. The manufacturer was not notified of the failure. The approximate vehicle failure mileage was 4,500 on a new installed engine. The tire failure mileage was 2,000.
We were traveling home and our TPMS indicated a tire failure. The PSI starting dropping rapidly. We took the tire off and found that only 4 " of rubber holding the back sidewall together on the tire. I then inspected the other tires on the car (which were purchased and installed at the same time) are showing signs of failure as well. All of the tires are 255-40-r19 We had a family of 4 in the vehicle at the time of the incident.
My tire is a 255 / 40 ZR 19 model, speed rated 100W. While rotating my tires I noticed catastrophic tread separation on the inner sidewall of the tire. The separation is scattered, not all in one section, and in total covers about 1/4 of the total diameter. The underlying belt package has separated and steel wire is plainly visible at distance. The tire was still holding normal pressure at the time of discovery and there was no indication of the separation from any pressure devices or anything other than visual identification of the issue, which was only possible due to a routine tire rotation. Driving conditions since installation of the tire have been ~85% dry weather at speeds no greater than 85mph. A long haul trip from San Jose, CA to Los Angles, CA (~675 miles round trip) occurred 1.5 weeks prior to discovery.
Complaints are voluntarily submitted to the NHTSA Office of Defects Investigation and are not verified by NHTSA; they represent owner-reported problems, not proven defects. Counts can be useful as a relative quality signal across comparable tires or vehicles.

Lionhart lh 501: what the numbers tell you
Manufacturer treadwear data for the Lh 501 is not publicly listed. This is common for OEM-only or track-day tires that don't carry a US treadwear warranty. No mileage warranty is published for this tire, which is typical for performance summer and track-day rubber where the manufacturer doesn't make wear-life claims.
Cabin noise data for this tire is not published by the manufacturer. As a general tire built for the passenger segment, the Lh 501 is positioned against direct rivals within the same category. Comparing it to a tire in a different category (e.g. summer vs all-season) makes the spec sheet misleading because the design targets are not the same.
The Lionhart Lh 501 has been part of Lionhart's catalog since its introduction, and remains a current-production model.
