It's not safe to run a tire which width is similar or more than your wheels.

 

why isnt it safe that what i want to know.

 

ok here is the 350z i was talking about it had on 275/35/18 tires and the tire buldging tire.




so this makes me think that since the Z has a 8.5" wheel like the oem 19's do i to can run 275?

am i wrong?

 

Sk8, if you're refering to the pic shown above I see no dangerous buldge
and no reason not to run 275s. Since you're using 19" rims I'd
run the 275/35X19. 40 series tires are used on our cars with 18" rims
when you run 19" the profile should be 35 series....I approve this message!

^agreed. you should run 275/35. I know the OEMs are 245/40/19 in the rear, but 40% of 245mm means the side wall is 98mm (tall). However, running 275/40/19 means 40% of 275mm will be 110mm, while 35% of 275mm is 96.25mm, which is much closer to the original height of 98mm.

hope this helps

 

haha i feel like sk8bo4rdv i dont understand wheels and tires and offset and spacers.. ther needs to be a class.

 

haha thank you sir! im going to be running 275/35/19

and hopefully now u guys can say its safe to runn wider tires than 255's on an oem rim

hahaha yes indeed sir. there need to be a class or a sticky thread.

sticky this thread for future reference

 

ok now another question i was planning on running 25mm spacers on my oem wheels all around which are now on 245/40/19 Front and 255/40/19 Rear. what size spacers would look agressive without fender rolling if i went with 245/40/19 Front and 275/35/19 Rear.

so would i go 25mm spacer in the Front and 20mm spacers in the Rear since i will be having wider tires now bieng 275/25/19?

 

20-25 fronts

15-20 on the rears depeings on your tire set up.

 

if I go 25mm all around I will need to get my fenders rolled right??

 

Not too sure.. I know for a fact that the fronts are really really tucked.. 25mm on the rear may require you to roll your fenders.. I think especially if your are rolling around on 275's.

 

ok cool thanks alot. i guess ill run 20mm spacers in the rear. ill mount the tires on first then see how much space i have left for nice agressive look.

 

thanks for all all the help guys.
so 275's are the absolute widest tire u can run on oem 19's for people who may have the say question as me in the future. =)

 

why stop at 275? Stick a 295/30/19 on it and call it a day.
