Yeah, i'd expect the 195/55R15's to be in the 4K+ range also.

On my 215/50R17s i had to settle first with the LM703s as there wasn't any other tire available in that size when i bought unless i coughed out 8.6K per tire for the Toyos or went for a China or Indo brand i'm not familiar with. I wanted the Kumho Ecstas but they had no stock either while the Solus was already over 6K and reviews pegged it at the same level as the LMs anyway. I just keep the air at 34psi like with all my other tires before. I've had the 702s and 701s on old cars in the early '00s and thankfully i never had bukol problems since we do keep the air pressure high and the roads I pass are generally predictable when it comes to ninja potholes.
