are u taking wind resistant into them calculations , i think the question is in general do wider tyres have more grip than skinny tyres not do 225 goodyears on a supra have more grip than 235 falkens on a ford at 34.6759657842 degrees

Hahaha :laughing-smiley-014:

Plus fat tyres look hektik.

Taken from the tire bible. Wider tyres don't always mean more contact area/more grip.

In general, I would assume wider tyres would have more grip.

Short answer, here is a good if somewhat detailed explanation.

http://www.autospeed.com/cms/A_108915/article.html - but you may need membership to acess it so i'll summarise. Grip is related to the coefficient of friction of the rubber compund of the tyre. This is in turn effected by heat. All things being equal Narrow tyres will generate more heat, thus depreciate quicker and lose grip faster, they also have less temperature stability. So a wider tyre can dissipate more heat, have greater temperature stability and should last longer. Thus given the same compound a wider tyre will generally have more grip. Pressure also plays a large role and dictates contact patch. Narrow tyes do have lower rolling resistance and are invariably better for fuel economy (once again provided they are at the correct pressure).

So yes $800 a tyre pirelli 225s will likely have an immense amount of grip due to the compound of rubber used. However as I understand it 265s can get away with a compound less advanced to result in the same amount of grip (they may also cost less), or with as advanced a compound should provide even higher grip levels and hopefully last longer (once again all things being equal).

wide tyres are always going to give a better amount of traction then skinny one's. When it comes to handling a wide tyre will give better grip, aslong as the wide tyre has wide wheels to match, the worst thing is to have tyres that bulge out over the rims alot as it gives a shit load of roll in the side wall of the tyre, which means you lose feel through the steering

when i raced karts we wernt aloud to use wet tyres at all . so if it rained we pumped the tryes right up so only the centre of tyre was on the road . less hydroplanng hence you could drive faster . not sure if i would like to try it out on my skyline tho

lol @ ^

lets face it, the broad answer to this broad question is - wider is better.

your getting too technical.

think of it this way. these two guys had a few beers, watching ralph tv, maybe some cones, and then 1 says skinny tires are better than wide.

what do you do?

*SLAP* i'm rick james bitch

You are 1000% right mate thats what happened i was have a few drinks washing my car and my mate was saying how my tyres are to big and his his skinnyer tyres griped betta, and funny enough we had another disagreement tonight about it again.

so far i have seen fatter is better and sum people have quoted which is the truest thing i have herd which is "THIS IS THE ONLY TIME IN LIFE WHEN FATTER IS BETTER"

thanks u to0 every1 so far

lol this is a big bug of mine, i HATE...absolutely cannot stand !! seeing any car that is relatively performance oriented on skinny tyres, i have 255's and i still think theyre too narrow haha, but they do look good from behind. aside from the better traction i think wider tyres give you more road presence, make your car look more beasty :)...if he wants thin tyres tell him to stick to a bike

p.s. to whoever was talking about in the wet thinner is better, im sure thats only to a certain extent, would have more to do with tread right ?

ROFL!

i had crappy 245's, and now have federal 235's.

it grips alot more than it used to.

i guess it's all down to compound and quality!

Fat tyres man, stretched!!

Looks tough as. I got stretched 8.5" wide on the back of my R32.. soo nice when you see it cruising from behind with all that camber!

I want wider though, but 8.5" just tucks in under the guard though.

how about on the front?

does a wider tyre offer more "GRIP" during cornering compared to a skinnier tyre?

all other things being equal.

say on the same car, on the same day, same corner, same brand and compound of rubber, same speed etc..

put on a set of 255's all round, then same thing with 225's all round.

which tyre offers more "GRIP" during cornering/turning?

staightline in the dry is obvious.. bigger contact patch is better for traction.

2 degrees neg camber on my rears, 18x9.5 rims with 235's stretched on there >_<

Very good way to burn through tyres and not as efficient as it could be, but it looks the goods

I showed my mate tonight and he said but im not talking about a drift car like every1 on here are. which i had to recorrect him by saying over all and he still beleave skinnyer is bettta so the 2 people who voted i rekon your skylines must look very um diffrent with 185s on it

running a fair shithouse 185mm tire on my stockies with full tread doesnt compare to running bald bridgestone grid 2's with 255's on the rear and 235s on the front.

bridgestones absoloutly shat all over these cheap as chip tyres i got on at the moment.

i voted for skinny because i have a non turbo, i like to think it handles better then it really does. especially having shitty brakes and an auto tranny.

who am i kidding? im humming for a 5 stud conversion and some decent rims and tyres......also a turbo and a manual gearbox....in other words a completely different skyline.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
