Hi Sajeev,

{the usual crap about long time reader, first time poster} I know you just answered a few emails about tire / tire size, but this has been sitting in my drafts folder for a while (the efficient side of me), I’m going to send it off before you answer more questions about tires..

My first question to you was ORIGINALLY about my now departed ’97 Volvo 850 a few months back when you were asking for more questions, but I answered my own question after reaching 3 pages of problems and issues. So I traded it in, more or less at scrap value, for a ’09 Lexus GS450h which came with a nice set of performance summer tires at 245/40R18. And as they say, winter is coming, and I’d be foolish to drive a RWD with summer tires north of the 49th. I’m planning to run 2 sets of rims + tire, got my eyes on some not so shinny Nokian “Hakkapelitaeraerfdaf?” R2 tires, but they are $300 a pop at that size.

  • D "smaller vehicles" - sorry, that's way too much common sense! Americans won't go along because clever marketing convinced us our egos need big@ss trucks, which give auto manufacturers the profit margin they want, and everybody feels vulnerable now unless they too have a huge vehicle. Lower speed limits could help, but no politician wants to push that losing policy. We'll just go on building more lanes and driving faster and faster behind our vehicle's tinted privacy glass.
