WANTING to buy tires for...
WANTING to buy tires for my Car....
currently have 225/ 45/ R17s on it per factory, owners manual says
alternate size is 245/ 40/R17
will the 245/40/17 lower the car stance or is the circumference of the 2 sizes the same .?
my concern is I do not want to lower the car any closer to the ground - this keeping ground clearance same as now.
I look forward to hearing from you soon,

ok..... that puts it in better perspective. Thanks for xtra input--- i like the idea of having a slightly wider footprint, a little more rubber on the ground too........I have to avoid running over dead skunks in the road now cause even their dead bodies impact the undercarriage...yuk.... lol and ur right .13" ain't much :) so I'll go with the 40's.... THANKS AGAIN !

you are welcome. please kindly take care to rate my answer
