When you put on bigger rims it messes with the speedometer correct? How do you compensate for that? Do you get the cluster retuned from the dealer or something?
 
you could try and get a wheel and tire combo that is the same or close to the factory wheel and tire combo
 
Several place sell electronic speed adjusterd or go with an sct tuner and they can adjust too

SCT yes, speed adjuster no. The LS doesn't have a single vehicle speed sensor. Instead it calculates the speed based on the ABS wheel speed sensors. The signal from the ABS to the cluster is digital data, instead of a speed signal.

If you want the ABS and AdvanceTrac to work correctly, you'll have to keep the total (wheel + tire sidewall) diameter the same as stock, as indicated by LS4me above.

Not if you get the correct tire size.

Give us the size of your wheels and we will help out with the size.
 
Meh, I was looking at the Senta wheels from the 09 XF. I think they are awesome, but if it's going to mess with stuff I'll probably just get something of the same diameter

You missed the point of the Tire Diameter Calculator, You first put in the size of your stock tire, ie. 235/50/17 which the calculator will tell you that you have a diameter of 26.3 inches so you then start putting in sizes that you desire (ie. rim size) and then choose a tier size that is close as possible to the stock size of 26.3 SOOOO a 245/40/19 tire has a diameter of 26.7 The calculator even tells you that at 60 mph you will be traveling at 61.1 mph


try the calculator out and you can find the tire you want. More important that the calculator doesn't tell you is how they fit with a lowering kit!! For that nighmare, you need the advice of the experienced guys on here!!
 
actually, you shouldn't have any problems at all, as long as your aren't changing the over all diameter more than an inch or two. They are usually a couple mph off anyways and when you measure the circumference and then see how many times that goes into a mile you get how many full rotations you get then compare that with the original tire circumference and you will see the difference is not at all staggering.
 
The sentas have to be 4 front wheels, the wheels will rub bad on the ls
 
Hmm, interesting. I could see trying to get ahold of 4 fronts being a pain in the ass. Look for wrecks maybe? Those of you who have, how did you go about it? Theres a set of Sentas for sale around my area, but they are $1700 (with rubber) and a normal 2 front 2 back set of course.
 
Many of us went with the sentas from usarim.com and had no issues. I would recommend them in fact. Talk to xford he has had his for the longest of anyone i can think of.

Check out the jag wheel database for pictures.

Yeah that's where I first saw them. On your car I believe. Love at first sight lol

i currently have 20" foose speedsters with 245/35ZR20's my speed-o is about 5 mph off but its really not a big deal to me. you get used to just driving 5 mph slower. also i dont rub at all which i was supprised about.
