IMO if you want to run that tire size with out too much pull prob going to want to stay at the 9.0 front and something like a 10.0 rear. Pretty sure that is the tire size of Brownmann's LS but he does run the 9.5 and 10.5 around +26 front/ +30 rear I believe but the tires do pull. I run my setup 225/245 same wheel width but they stretch hard and my offset poke quite a bit at ride height. I can only speak from my experience and I am unsure on the +40 for 9.5" and +34 on the 10.5 I know for sure it will bring the wheel set inward towards the body just not sure how much clearance you will have there.

 

 

You should be fine with that setup, however that +25 in the rear your gonna need to either pull your quarters or run lots of camber. I have Bugels and i'm doing 20x9.5 +25 and 10.5 +27. Front and rear fenders rolled flat running -1.8 degrees of camber all around.

 

the OP is running 19x11 Bazerias at +24 in the rear with just a roll, so i should be good with 19x10.5s +25 in the rear with just a roll as well i would think.

im thinking of running 30 series tires all around, 245/30 front and 265/30 rear... thoughts?

 

10.5 +25 on the rear with a roll will not tuck or clear the quarter panel imo just from experience on mine I had to shave the quarter panel all the way flush practically and pull about 3/4" to get the fitment. Also running a 245/35 to get the stretch as well to help the tire from hitting the lip.

 

It also depends on the faces. what works for one wheel, may not work for another. I believe DPKDavid is running something similar to what you have in the rears but in a 20". He needed to do work to make them fit.

 

Again just going to stress this for anyone looking to fit a rear wheel with similar size and offset 20x10.5 +25 (also depend on face such as UCF30_SD had mentioned) will need fender work even if not on air because of suspension travel. If you need pics I can provide to help. PM me separately.

 

I've found the sweet spot for minimal camber, bodywork is 10.5 et +30 on stock camber arms if your looking to tuck wheels.

 

 

That's not the point though my fellow Cl friend, here is my point 20" or 19" it will come down to overall tire diameter and also if you do not run a stretch to pull the tire away from the outer lip. Can you tell me the overall tire diameter for the rear that you will be running just trying to help save you some headache? Just as some advise the rears usually do not get rolled on the LS the metal is double layer metal and with the square insert for the trim, once that is removed if you attempt a roll it may dimple or "bacon" the outer quarter. Not totally impossible but just search it out and you will see most guys shave the rear lip but then you can run into metal separation just my two cents. so either way there is a challenge to do it clean with such an aggressive offset. Also a pull should be required to tuck these unless the overall tire diameter is less then 26.8" the reason being at that overall diameter with that offset the wheel/tire lands outside the body line I can show you if you like. Others here such as DPK have done the same rear fender work as I have and quite a few others so just sharing the first hand experience but again I understand this is with 20" and you have the 19" so possibly it will just fall into place with the lower profile tire and 1" smaller diameter wheel. I love your wheel choice and am excited to see when they come in!! Keep us posted!!

 

 

 

That would give a 1.98% error in the speedometer between the two tire sizes.

 

is this bad? or in the acceptable range...
