I am dropped on H&R Springs would these sizes rub? 245/40-19's on the front and 275/35-19's rear.

 

Should be fine. Many using that combo who are lowered. Will also depend on your wheel offset and/or alignment.

 

I plan to run the same, 45/40-19's on the front and 275/35-19's rear but on the vert, which will look like an H&R drop due to the weight. I plan to add 15mm spacers all around also. The rear will be going back to stock though as -3 deg camber will rub on the stock wheels without spacers. Currently test fitted 265/30/19 with the -3 deg camber.

 

Just got these tires... they're pretty nice. Loving them.

 

Also moved from Toyo Proxie T1R 285/30/20 to Hankook ventus v12 275/30/20 no more rubbing with Volk GT30 at +37. Love these tires! It seems it all depends on how well your bodies aligned since the rubbings only on one side, some folks can run 285 and have heard of one user running 305 with no rubbing, not me and I tried camber all the way out to 1.9... don't like the broken axle training wheel look to go further. There's only a .2" difference, but it's across radius, sidewall and diameter for a .8" difference in circumference. I should have went with 235/35/20's for the front for a perfect match, but stuck with 255/35/20 since I didn't have a rubbing issue up front...oh we'll live and learn... got an excuse to burn these babies .

I still need to give it the fat chick test though, I've also lost 15lbs and gained 2Hp...lol. Adds a whole new dimention to modding, tuning one's self.

 

That's what I plan on running when my stocks run out as well. Like cereal I'll be putting on spacers...just need to see what kind of room those tires give because they are so much more square than the stocks. I'm hoping 20 will fit, but know I might have to do 15.

 

When i had Tein S techs and 20 inch vossen w +39 i rubbed w Hankooks 285/30/20 but not w falken 285/30/20 ! 275 should be ok but you are on H&R so dunno plus a 35 series. Try it out.

 

I'd like to know if Hankooks are more square of a tire then T1R's???^^ As some know I'm considering makign the switch from T1R's to Hankooks, but I want to make sure I won't rub in the rear with the EXACT same specs. Right now my rear tire barely fringes the liner of the fender. I have NOT had to make ANY modifications nor do I want to.

 

Hankooks are more square than T1R, both are more square than OEM tires. I don't think the difference between V12 and T1R is huge...but if you are that close I'd do some more research before trying it.

I ran T1Rs on my sedan for years...and I really like those tires. I got about 15K out of them running -2.5* all around. I was pretty impressed, and they were quiet the whole time.
