Uneven Tire Wear
Posted: Mon Jun 03, 2019 10:48 pm
Hey thought I'd post this to continue my karting education.
What can you tell me about this tire wear? Now don't be fooled by the pic, I should have snapped it before I changed it, but this tire was just flipped tonight, so that outside edge was actually the inside edge of my front right tire.
This just developed at the last T&T. Prior to that T&T the only change I made was to adjust the angle of my steering column (see second picture, I moved the blue collar down about 3/4 of an inch.)
I measured multiple points of each rim to a stationary point on the chassis before adjusting the column to see if there was any change in the alignment, nothing changed a hair in terms of toe I'm certain. Additionally I had Joey install a brake side seat strut (so I now have 1 on each) about 30 laps before going home. (Didn't notice the wear until end of the night, so can't attribute it to the strut persay though certainly felt the second strut helped my turning for sure after a few laps.)
My lap times were by far the fastest and most consistent this last T&T and did about 100 laps (have done that before without seeing any uneven wear.)
So my thought was this was a sign I was transferring my weight better from the improved driving position, and maintaining more speed in the corners and on the basis of the track direction maybe this is why this developed? (Since all the fastest corners are left, more pressure/scrubbing on inside right through corner?)
Is this an appropriate evaluation? And should I be adjusting anything to compensate for the wear (other than flipping them?) What does this tell me about my driving (if anything and what to work on?) My pressures in the front were about 13.5 (14 in back) so far that's given me the best result but going to test higher pressures again this week.
Thanks for the feedback.
