Need to make a decision on a new set of tires quick. Presently have the 38" PJ's but would like to consider others. Really diggin these Iroks. After 4 years and 27.5K miles, 2 PJ's are cracking somethin ugly right between the lugs. One crack is so bad it went flat. So thinking about 4 more PJ's or 5 Iroks. The PJ's got me worried cause I don't want to see any more cracks like these again. 38" Pj's are recommended for a 11-13" rim and the Iroks a 10" rim like I run. I don't know if that has any contribution to my situation but I feel a little more comfortable going w/ a recommended tire/wheel combo this time. Any input is appreciated!!!
