which tire size should i put in the rear of my Z?

[07bluerocketZ]

i was thinking about keeping teh stock tire size in front and going with 19'x10' in the rear....what do you guys think????

[quietkilla6]

i think that would cause major over steer but im not sure. keep in mind you need to focus on tire height also. and infact IF your back tires are more that an inch and a halph taller than your fronts, you will have major brake problems. and an inch and a halph is an easy screw up. also for every inch of height difference from stock height you lose and .8 pound of torque (this is all second hand so if anyone knows this is wrong please correct) but i went with a taller tire and i kinda regret it. Ive got 9.5 in the back and it seems to be hella grip to me.

I virtually have the same set up and it works GREAT!

I have the 19x10 rears that came with the new car (grand touring coupe) and am now runnning 275/35/19. All is fine or just run the oem 265s. 19x10 will work fine in the rear on yours too.

[07bluerocketZ]

so you think that going with 18'x9' in the front and 19'x10' in the rear,would work great???

YES, and either 18x8.5 or 18x9s in the front. Remember to use the proper inflation and torque plus re-torque after the first 100 miles or so.

I found an article on 350zmotoring-wheels&tire garage. It really helped with my tire selections. I went from stock 17's on the front and rear. to 19's on the front and 20's on the rear. I kept the tires within .1 in of stock. front 245/35/19 and rear 275/30/20

^ please post a pic of your car...on 19s and 20s.

[BlackSmoke]

yeah post a pic of that I want to see how crazy a 30 series tire looks on the rear. It will look like you a driving on just a wheels.

do you know what your weight is with tires?ive got 245/35/19 on 19x8.5 front and 275/35/19 on 19x9.5 on the rear and my volks weigh 48pounds in front and 55 pounds in the back, i thought that was kinda heavy...the stock 17s weight is like 43 and 46 with stock tires

Whatever size you decide just make sure the tire in the front is 0.7"~0.9" shorter (height wise) then the rear, otherwise it will trigger bad episodes of VDC action. If you dont know what that is, its a form of a traction control device that monitors front and rear wheel speeds. If you put a tire too short in the back or too big it will cause your car to buck and lose power as the computer will think you are experiencing unexpected wheel spin.

On my stock, performance trim, 18" wheels I am running harder compound, Falken 275/35's combined with stock size BFG KDW2's on the front. The BFG's are really sticky and since the Falkens are wider, they do give a little bit more stable grip but since they are harder compound I can induce oversteer pretty liberally, . I like the setup, but we'll see how it does this autocross season. Probably I will go back to stock size or maybe even slightly smaller in the BFG's (225 like the fronts if possible) to make the car more level handling wise.

I plan on running some 18 x 9-9.5 in the front and some 18 x 9.5-10 in the rear depending on what rim I go with and the availability. I plan on putting some 245's up front and 275's in the rear. It's similar to what my friend is useing and he says it works great.

[iowas300z]

I have 245/40/18 in the front and 275/40/18 in the rear, and I love the setup working great hope it helps.

[gtnmwet]

will a 245 40 19 work up front (half inch taller than stock) or should we stick to 245 35 19's?

[bmike818]

^^ what size rims do you have. Becasue I want to sport the same tire size as well. I have 18x8s up front and 18x18.5 on back.

...thanks

[iowas300z]

18x8 in the front, and 18x9.5 in the rear.

[rmezz13]

I am running 18x10.5 rear and 18x8.5 front. rear tire is Falken FK452 275/45 excellent grip and overall performance.

Well they may seem heavy but that is the diffference in weight between those 17's and the 19's. You should be fine with that wheel / tire package. I hope the offset of the wheel is proper to fit the tire correctly in your fenderwell. Post some pics after you put them.
