I recieved a ticket in a school zone due to missing the blinking yellow lights on the reduced speed limit sign. The sign looks like it sits more than 50ft from the side of the road and up on a hill. ...
Im confident but still nervous.
What are some things that I should know & do, that i haven't been told already?
like something they could fail me for that some one wouldn't ...
Can I change the width of my tires?
I have a Peugeot 206 SW with 205/45/16 summer tires. I now need to buy winter tires, but am finding that 205/45 tires seem to be considerably more expensive than, say, 205/55 or 195/55 (all for 16 inch). Maybe 55% height tires are more standard and therefore cheaper?
195/55 is the cheapest, so if this is an option, I would definitely switch. The question is, given my 16 inch rims, can I use a tire with a different width? I understand that both 205/55 and 195/55 will result in a larger, taller tire. What are the implications of this?
45 profile means 45% section height, so to preserve the same height going to a 55% profile, you say
N*0.55 = 205*0.45
N = 205 * 0.45/0.55 = 167.
So you'd need to put on 165/55 to preserve the same height, which sounds maybe ridiculously narrow. Or the reverse being true that if you run the 195/55 it would be much taller.
ok 16" = 406mm
height with 205/45 is 406mm+2*0.45*205mm=59.05cm
height with 195/55 is 406mm+2*0.55*195mm=62.05cm
Difference in final drive ratio (speedometer correction)
62.05/59.05 = 1.05... so speedometer and odometer will read 5% slower than actual speed or mileage.
When I look on TireRack.com I find what I think is a reasonable deal for a tire in your original size
Dunlop SP Winter Sport M3
for $117 each. And when I search for 195/55 the prices are similar. Maybe supply and demand are different by country where you are... usually what has the best price is what sells the most volume.
