BF Goodrich KDWS tires....anyone running these?
The reviews on TireRack and Discount tire are generally pretty good on these tires. The price is great.
Was thinking about getting a set for my '06 VDP.
Anyone have experience with these on their XJ??

RE: BF Goodrich KDWS tires....anyone running these?
I put the original size 235/50ZR-18 KDWS on my fiancee'sXJ8 at one tire shop March 2008 (about $280 for the set, he boughtout a large tire warehouse that went out of biz, passed savings to us).
Then I had local Goodyear tire shop fill them with nitrogen ($30 for 5 tires) at 37psi front, 33psi rear.
Moved it to the alignment rackand I specified these settings:
FRONT
camber -0.6 to -0.4 deg:adjusted to -0.5 deg each L&R(was -0.6 L, -0.4 R) .
caster 7.4 to 7.8 deg: compromised:adjusted to 7.1 deg L, 7.2 deg R (was 6.6 L out of spec, 7.2R) ... it was not possible to loosen bolts safely R side to add more caster, so the L side was brought up just under the R side: this is a USA car, drive on the right, so R caster should always be slightly more than L caster to prevent drifting to the right .
toe in 0.00 to 0.01 deg each side: adjusted to 0.00 deg L, 0.01 deg R (was -0.03 L, -0.08 R: yes it was toe-OUT) .
REAR
camber -1.2 to -1.0 deg: left alone at -1.2 deg L, -1.1 deg R .
toe-in 0.00 deg each side: adjusted exactly to that (was 0.07 L, 0.00 R) .
Very happy: better ride (even with 37/33, nitrogen molecules are larger than oxygen molecules ... they also appear to leak less) and steering response than the orig Conti H-rated long wearing tires (that lasted only 24,000 mi). I'm in Fl, so no snow, but great in dry and rain. Very quiet, about 7,000 mi and almost no wear. Picked up 0.5 to 1.0 mpg (prob due to removing the F toe-out andR toe-in)!! No longer crabs/kick-back thru the steering wheel on pavement changes, so never have to correct anymore. Perfectly straight at 80mph even when pavemnet gets rougher. Even my fiancee noticed the difference, and she does not notice these things usually.
I will also post athread on Wagner semi-metallic pads (low dust) and Tri-net slotted & zinc-washed rotors ... changed the F, still have to do the R.
Anyone know how to get the brake pedal firmer? Way too mushy ...

RE: BF Goodrich KDWS tires....anyone running these?
Her car is a 2004 XJ8 VanPl ... nice car, but ...
I am 6' 3.5" , and I do not fit in it well. Pedals are adjusted to floor, seat all the way down & all the way back, and I could use another 2 inches of leg room. Dealer says I'm not the only one at my height and taller who isnot happy about the lack of room. Under dash is not good: only 1 pair of dress shoes will allow me to go from gas-to-brake quickly without clipping underside of dash. I will prob reform the cover so I can wear different shoes ...
Would really like specific solution to mushy & long brake pedal travel. Dealer did a brake flush in 2006 or 2007.
Idid Wagner semi-metallic pads (low dust) and Tri-net slotted & zinc-washed rotors from eBay ... changed the F, still have to do the R. This helped just a little, but have a long way to go.
BMW745ion19s: what changed on 2006 and newer brakes? If master cyl is different and fits a 2004, I will consider swapping it out.
The alignment ... is my acquired knowledge of the last 30 yrears of autocrossing, suspension design, understanding how suspensions work, ... I also do CADD (computer assisted design and drafting). The specs I picked are not radical, & within Jag specs. I picked mild settings ... she drives the car 90%. If it was me, I would have had just a hair toe-out, -0.5 deg more neg camber, anothe =1.0 to 2.0 deg more caster.

RE: BF Goodrich KDWS tires....anyone running these?
JC im not quie sure but i saw this on edmunds.com before:
What's New for 2006 The Jaguar XJ receives a few refinements for 2006. Both V8 engines see modest increases in output, and the braking system has been revised for a better feel. New features include chrome-mesh grille inserts, laminated side-window glass for reduced road noise, satellite radio, Bluetooth wireless connectivity and an upgraded tire-pressure monitoring system. For 2006, there's also the Super V8 Portfolio, a new top-of-the-line, limited-edition trim level.
I know for a fact on 06 and up s types ( had lots of loaners) the brake pedal feels much quicker to respond and make my R brakes feel much more spongy...However when you really get in them the Rs do grab quite harder
also in 06 R cars brakes were diff then 03-05 R systems
Im 6'1 though and have never had a problem with my height driving even my S. I honestly like to sit with the backrest up more then most people so i have good posture. I do feel for you with the dress shoe thing. When i wear dressy bally or prada shoes they often do the same thing [
] i wear tons of cole haans though and never have a problem.
hope this helps! maybe brutal knows or can find out whats diff in 06?

RE: BF Goodrich KDWS tires....anyone running these?
Hi Joe V, my car is the same as yours and the brakes are solid. You may just need to bleed them out or perhaps someone has installed softer pads (organic or the like)the Jag won't respond well to those. BTW, I am 6' 0" and have the seat all the way back but not all the way down. My wife and I both had Avalons before I got the Jag and the seat in that still had about 3 inches of rearward travel left. We were looking at both cars in the driveway and the Jag appears to be much larger on the outside but Toyota used the available space inside and provided much more leg room for both the front and rear passengers.

RE: BF Goodrich KDWS tires....anyone running these?
They were installed on the new pre-owned '04 XJ8 i just picked up. I noticed some shimmy 50+mph and when breaking. Inspected pads and rotors and found a tad of rust on the rotors which may have caused the little squeaking I heard when braking. I find the tires to be a bit noisy and while I haven't run THIS XJ8 on anything else, the OEM tires (continental ?) seem to ride smoother and quieter. I'm considering changing out these tires - or I may rotate and balance and see if that changes anything... the local Jag dealer 'strongly' recommends changing the tires to Michelin or Conti not sure what to recommend!

Consumer Reports on Nitrogen; and again here; plus you've got to love what what the NY Times reported more recently. And there's more than you could ever care to learn or discuss about nitrogen in this guy's blog.
ORIGINAL: JC316JJMoved it to the alignment rack and I specified these settings:
FRONT
camber -0.6 to -0.4 deg: adjusted to -0.5 deg each L&R (was -0.6 L, -0.4 R) .
caster 7.4 to 7.8 deg: compromised: adjusted to 7.1 deg L, 7.2 deg R (was 6.6 L out of spec, 7.2R) ... it was not possible to loosen bolts safely R side to add more caster, so the L side was brought up just under the R side: this is a USA car, drive on the right, so R caster should always be slightly more than L caster to prevent drifting to the right .
toe in 0.00 to 0.01 deg each side: adjusted to 0.00 deg L, 0.01 deg R (was -0.03 L, -0.08 R: yes it was toe-OUT) .
REAR
camber -1.2 to -1.0 deg: left alone at -1.2 deg L, -1.1 deg R .
toe-in 0.00 deg each side: adjusted exactly to that (was 0.07 L, 0.00 R) .
FRONT
camber -0.6 to -0.4 deg: adjusted to -0.5 deg each L&R (was -0.6 L, -0.4 R) .

Thanks for the advice. Went ahead and bought a set of the BFG.
Nice tires. Quiet, and a bit firmer ride over the stock Conti's.
Hard to beat the value of these tires too @ $80 each.

From Tire Rack? I bought a set, too.....my third. I have them on my XJR and also had them on my Mustang GT, and love 'em. I bought this set becuase of the bargian price....I won't need them for a few months.
The first ones I bought a few years ago were more like $170 each !
Cheers
