Default Will 28" tire fit easily

I was going to go with 26x10 ET drag but they look to be out of them at Jegs. Whats it take to make a 28x10.5 ET drag fit on a formula? Suspension is all stock.

I realize it will probably be over kill on motor with just cam/stall but I am tired of being inconsistant trying to bracket race.

More info would be appreciated. IMO 28" tall tires are overkill for you. I have done get on a 26" tall ET Drag and I race a 6 speed car and leave nearly off the limiter.

The best thing you can do is get a line lock kit if you have not and some basic suspension mods like LCA's and TQ arm.

I have 15x8 wheels. I only want to go 12.00 on motor so if the tire kills ET it would be ok. The car should run mid 10s on spray so a 28 will definatly benefit me there. Right now I am on ET streets and they are so in consistant its impossible to bracket race. One pass low 1.6 short time next pass mid 1.7 short time.

I have noticed my car gets sideways sometimes during a burnout when I just hold the brake and pretty much ends the burnout. Would a line lock help with that?

i cut my bump stops off and hammered in some of the inner well area. adjustable phb helps too. stock shocks might be a little weak though so you may bump up top.

a line lock imo is not going to help your car from going sideways in the burnout box. It just keeps that front brakes locked while releasing the rears, so your not burning up your rear brakes. You might need to try to walk out on the track, and look for the groove you might be pullin yourself into and line up better with that. again, just my opinion.

A ET Drag is a fine tire and I swear by it. Since its an automatic I can virtually guarrentee you that you do not need a 28" tall tire.

But do as you please.

As for the sideways thing, get more water under the tires. Mash the throttle in 1st and hold the brake, sometimes a worn posi can pull you or your brakes are biased.

Like said the line lock leaves the rear free to do as they please. Given the car has a good rear and some water under the tires, it will burn straight. Roll out under power and release and you will notice the tire grab hard.

Good point on the groves. I have noticed the car only gets sideways in the left lane burnout box at my track. Im going to try and pull farther forward next time out.

I agree with BSM. Make sure you've got water on the tires. As you roll into the waterbox crack the throttle real quick to spin the tire in the water to get the whole tire wet. Move out of the water slightly. Then quickly get the motor up to about 5000rpm's, for about 3-4 seconds and roll out as BSM stated. As for a 28" tall tire I ran them all last year with no problems with a stock rear end and didn't have any clearance issues what so ever. Car runs consistent 1.56-1.57 60ft. all day long. Good Luck.

FYI my M & H 27 x 10.5 tires rub with adjustable control arms. I would not be able to get 28's to clear my setup.

You can always go with an anti-sway and preload it to go straight also.

Sound like some are clearing some arent. I dont mind beating or rolling I just dont want to have to buy lca, shocks, or phb. What do you guys do about the bumper? It looks like it would be very close to rubing with 28s on

I have 28"s with a 10" wide wheel and they fit fine, although it is a tight fit all around. I had the same problem as you everytime I did a burn out I was getting sideways and it was hard to hold a burn out. But like the others said to do, I started turning my tires over real quick in the water box to get the whole tire wet, moving foward a little bit, then doing my burn out and it was a hundred times better. What type of tire are you on currently? When I was just cam and stall on stock suspension I was dead hooking and cutting consistant 1.66-1.67's on only a 245/50/16 Nitto 555R. 28"s are going to slow you down on your short time and over all et.

seems like if your rearend is square, you won't have a problem staying straight in the burnout box. I had problems with the stock rearend and no linelock... when i did the 9" adjustable LCAs to square the rear my car stays dead straight in the box everytime. That was when i had a 6 speed in the car. To fit a 28x10.5 you need adjustable LCAs and PHB to center the tire. I had to roll the fenders, and lots of BFH, didn't have to touch the bumpstops though. Probably depends on your wheel setup, I imaging the backspace varies a little from different manufacturers.

Best on motor is 1.60 but recently is been high 1.6s to mid 1.7s its just spinning soon as I take off. I have never had this problem with ET streets before.

Maybe the track prep just isnt as good lately as it was in the past. Like I said, I put mine on and they fit fine. But others have to cut bump stops or bring out the hammer, I guess its hit and miss. If you dont mind losing a little speed and 60' time then I would get them if your just trying to be more consistent. Maybe play with your tire pressure.

My 28's required alot of BFH to get them to clear and they still rub very slightly during my burnout but not enough to do any damage.

Burnout problem seems fixed. I just needed to spin the tires in the water and pull farther forward to stay out of the groves and ruts. Car still didnt hook only cuting 1.68 on motor and 1.63 on spray.

Hell I didnt know you were on spray, how much of a shot? Like I said, my 28"s kill my times on motor...but they are awesome when I use the nitrous. You would probably be alright if you got the the bigger tires.

125 right now, I want to be able to spray a 150 off the line. Im looking for high 1.4 short times. How much did 28s hurt you on motor?

I have heard from many of the "old timers" that it is not good to crack the throttle in the water box because it slings MORE water up into the fender wells and then the water drips back down off of the finder well onto the tire when youre sitting at the tree and when you leave, you spin.

I dont ever do it because it makes sense.

Just a little advice, and my .02 cents.

Also dont do a burnout in the waterbox. roll through it, pull out of the water then do your burnout. Again, this is just some advice and my .02 cents.
