They are 19 x 7.5 with a 42mm offset I am just wondering
so far they look good. with the proper lug pattern and the right tire size, you should have a perfect fit.
No what size do you recomend?
for tires, i've seen
225/35-19 215/30-19
and the lug pattern 5x114.3mm or 5x4.5"
Yeah I got the lug pattern but I wanted to ask have you seen or know if i would be able to put 225/40 on there or would that not work?
stick w/ 225/35zr19. 225/40zr19 are too tall (1.3% vs. 4.9% difference from stock [205/55r16]). you wanna stay around +-1.5% from stock to keep the TCS/ABS and speedo/odo operating w/in correct standards.
so what if u have neither...and is therr anyway to fix the speedo...or how can u kno how much faster/slower u are goin...cuz aint no way in hell im ever buyin 35's againQuote:

i don't think there is a way to adjust the speedo for much percent away from stock...
you can calculate the diff in rolling circumference w/ a little math:
first you'll need to convert all measurements to either standard or metric (tires are metric but rims are standard). 1" = 25.4mm. next take the stock wheel / tire size and figure out how tall it is (diameter)... 205/55r16. to find out how tall a tire is you take the series (profile) times the width. so in this example 0.55 x 205mm = 112.75mm. now take that times 2 (tire on top and bottom of rim) plus the height of the rim (16" converted to mm is 16x25.4mm = 406.4mm). so 406.4mm + 2(112.75mm) = 631.9mm which is your diameter. so to finally find the rolling circumference use the formula Circumference = Pi x Diameter. Pi is approx. 3.1416. rolling circumference of stock is 1985.17704mm.
now just do the same calculations fo the new wheel/tire combo and divide the rolling circumference of the stock by the new circumference and the difference from 100% that you get is how fast or slow your speedo will be... if the quotient you get after dividing is over 100% it's faster than stock and if it's lower than 100% it's slower.
ok my head hurts now, i need to go to sleep.
