Default Need tires size help MRR M755 Z51 replica wheels

I have searched a while and haven't found exactly what I need to know yet regarding tire size on these spec of wheels. I also heard about cracking fenders but haven't found any threads about that due to tires being too wide or offset issues.

I have a stock ride height Z51 with 19x9.5 50et and 20x11 73et wheels. I know they don't have the best offset, as they stick out a little, but I need wider than stock tires ASAP as a bad alignment has worn the inside of the fronts and outside of the rears. The 245/35r19 and 285/30r20 are too stretched on the 1" wider wheels. I would like to fit 275/30r19 and 305/30r20 on the car but don't know if they will rub and/or hit the fenders to the point of doing damage. The 275/30 have a better circumference (in keeping the F/R ratio for the BCM) than a 265/35 although I think the width of 265 should fit better. I only daily drive and will most likely be going with all season tires as the MPSS basically sucked for all but the 90+ degree days.

Does anyone know if I can get away with the tire sizes I mentioned? There aren't any in stock so I would need to have the tires ordered and that is where I am running into resistance with tire shops here, kinda a catch 22 as they won't order if they don't know they will fit or rub.

Thanks in advance!

Default Minimal clearance when almost in 2 wheels











Car is up on my drive with 1 front in the air and the other rear half in the air to give an idea of wheel travel and clearance. Any thoughts?

The front will be fine. You will never be at speed with the wheel turned that much so a 265 or 275 will fit fine there. The rear will be close with a 305. I run a similar size rear wheel , but with a 76 offset moving the wheel in 3mm, am lowered on stock bolts all the way and with a 305 30 20 have to run -1.7* of camber and have trimmed my rear fenders to get them to clear.

That isn't stock ride height. That's just stupid low.

Thanks for the info, looks like I'll probably end up with 265/3519 and 295/30/20. I'd like 275/30/19 but it seems like it's harder to find with a matching rear. I think my driveway will be the hardest to deal with like you implied, but hopefully manageable.

The comment that said thatís stupid low is totally bias. That car sits GREAT!!! The stock height looks horrible. If the op wanted a 4x4 Iím sure he wouldíve got one. Nice car man.

Wider tires/lower car may not always be possible without potential issues. Something to do with the Laws of Physics as I remember.

Two items occupying the same space at the same time will do damage to one.
