So pulled the trigger on a set of LX25's on Tuesday, from Discount Tire; 235/55/19 101H, which are cheaper than 225/55/19, don't rub the suspension that I can tell, and only a hair difference on speedo; 70/71mph on GPS vs 70mph on speedo/cruise display. The guys at Discount Tire said they have installed 235's on many CX-5 the last 3 years, as 225's aren't that popular and more $$. There might be a slight drop in MPG. Will monitor, as I reset the counters at every fill.
Paid $831 for tires+installation+disposal, before tax. $183 each tire-only. There is a $70 rebate from Continental until Dec 31.
Got 39.6K mi out of the factory A39 (UTQG 300 AA). Hoping to get 80/85k or more out of LX25 (UTQG 740AA).
Even with Discount Tire filling them to *39 psi, there is markedly less road shock transmitted to body and steering over expansion joints and rough pavement, as compared the to A36. I know some of that is because there is full tread depth on the LX25 vs 3/32 on the A36, but the LX25 carcass seems more compliant. I plan to drop the pressure to 35psi and discern further improvements in shock isolation, vs loss of turn in.
The steering turn/response seems as sharp as the A36 (either at 7/32 or at 3/32). LX25 are noticeably quieter than the A36 on textured concrete freeways, and slightly quieter on blacktop--the A36 were very quiet on blacktop. Straight-ahead tracking seems very good--the tires don't readily follow pavement grooving.
*apparently their way to keep your TPMS from coming on with North TX Winter temp swings from 20F to 75F.
