I currently have 4 rota's
2 fronts are 245/35/19
2 rears are blown but they were 275/35/19

Today I got a good deal on some 275/40/19 so i bought them, Not doing my research and they are on the rims now

After alot of searching i found only one other person with that set-up, and he was talking about VDC problems, etc.

SO i gotta ask, is that true? I can get the them switched out for 255/40/19 for free monday but i gotta know if
Front -245/35/19
Rear - 255/40/19
will Work fine?

is there a % difference that it takes to Trip the VDC?

Please help i gotta go back monday. They didnt have any 275/35 grrrr

 

My understanding is that you should be shooting for about 3% +/- a small fraction of a percentage.

With that said:
275/40/19 is at 6.91% difference @ 27.66"
255/40/19 is at 4.74% difference @ 27.03"

Front is @ 25.75"

I would wait and find the right sized tire.
Either go with 275/35 or 275/30

 

ive read a few other posts with a guy by the name "Redlube" claiming a 255/40/19 works but
How did you calculate that %

A 255/35/19 would be a better tire if you want a 255 width.

Also works, thats what I use for my calculations.

 

i dont think you should put a taller tire on the rear its going to mess with the vdc, sell those and buy 30 or 35's

 

im so happy 03s dont need TPMS
