Re: Replaced totalled 2004 with '05 SRT6 Roadster
Personally think the tires have the most to do with hydroplaning. This is the time of year when we start getting frog stranglers, usually hit one or two every time I go to south Florida on the 'pike.
My tow car is a Jeep Grand Chrokee. When the factory Goodyears were about 1/2 worn I started seeing the TC light in rain. Switched to Michelins and no more TC. Now have three cars with Michelins, one with BFGs (because nobody else I trust makes big (255x70x15) 15s, the Crossie has Continental DWSs and do encounter the TC but usually on a hard 1-2 shift (stick). They have proven very good in the rain and the DWS06s are supposed to be better.
So IMNSHO the tires are the biggest factor in wet traction but is helpful if the driver has experience on ice especially Florida ice..
