Ok. Before I get harassed... I have searched, I have read, I just need this covered in a little greater detail.

To start off I have definitely decided to go with 245/35/19 on the front and 285/30/19 on the back. That said I would REALLY like to run 295/30/19 tires on the rear. Right now my top choice for rubber is the Continental ExtremeContact DW tires... NOT the DWS. I know this particular setup will work, and does with great success. Soo my primary questions are:
-Will the 295s work on the stock rim without any problems?
-If they won't work on these particular tires, are there others it will work with?
-If I run 295s on the rear, should the front still be 245 or should it go up to 255?

I read a thread, I believe on here, that a guy was autocrossing on his stock ISF rims running 305/30/19 Hankooks I believe.

No one gets harassed here

Even if the topic has been covered I think the point of the forum is so you can chat with other owners and experts not just read about it. I'm sure someone here will have a helpful response for you soon.

Thanks... That's very much appreciated. I am by no means an expert when it comes to wheels, tires, offsets, diameters, etc. I need some people, who do know about all of this to help me make a great decision.
Just for referrence... I am planning on my setup consisting of a K&N Intake, Elite p/p Throttle Body, ExtrudeHone p/p Intake Manifold, PPE Headers, and either a JOEZ or ISS Forged exhaust. Soo, traction is going to be a serious issue, as it already is for a lot of you. Down the road I am also considering a kit for a 150 wet shot of NOS... Just in case. ;-) lol

Some on the forum recommended the takeda intake over the K&N, with Takeda you can keep the 2 stage intake setting...with K&N you cannot

Sounds like your lexus is gonna kick major ass when you're done. California won't let me have as much fun as you are having!

Thanks jonjon, I appreciate the suggestion. I have been long since convinced of the K&N Intake for this car. Plus it's already installed. I'm hoping the car turns out to be pretty bad ass! =-) I'm after the most horsepower I can get. But either way I'm hoping to not get too much into opinions/debate of particular parts, in this thread at least (lol), that way I can figure out what to do about these tires.

I have never seen the 295/30/19 run on a stock ISF rear wheel, but I have seen the 305/30 that you mention, and it showed severe tire bulge. IMHO, the 295/30 would be too wide for the stock wheel. As most of you know, I believe I was the first to put the 285/30 Continental DW on my rear with great success. But, anything wider would be pushing it.

BTW, I'm running the Takeda intake and luving that too.

OK thanks. I considered the Takeda intake, it's functional and looks great, but chose K&N for the higher "claimed" horsepower. "Similar" numbers have been duplicated by independent testers. I haven't really done much research on the Takeda intake, as I have already chosen my destiny. lol

I'm also a little concerned about wheel weight... I'm sure I could search this but now I'm being lazy. =-) What are the stock wheel weights, and what are some great looking, lightweight, fairly "inexpensive" replacements that could run 305s? Sticking with 19 inch wheels. I'm a huge fan of Breyton GTS rims, but they are made to fit only a BMW bolt pattern which sucks! Is there something similar that fits our cars? I primarily ask bc I don't understand anything about offset and I wouldn't want to get something that won't fit.

Check this out:

Well the link won't work but if you go to tirerack dot com and enter your vehicle info then press the "wheels" button it will break it down by wheel weights

Here is the thread for wheel weight

One of our members has been working on a project to run 255/305s on the F.

Lou,

This might be a silly question but reference the 245/285 combo... Would you still run the recommend tire pressure that's recommended by Lexus for the oem 225/255 combo OR would you fill it a little higher/lower to compensate for the difference?

I've got another question about the sizes. I'm going to go with the Continental EC DW tires... The rears are going to be 285/30/19. I WAS planning on 245/35/19 on the front, BUT I just realized there is almost a $50 difference between 245 and 235... Would there be any adverse effect running the 235/35/19 tires on the front with 285/30/19 on the rear combo... Or should I just suck it up and put the 245s on the front?

Also, what's the cheapest place to buy? Thanks

As far as price, I would check out Discount Tire Direct. They are a sponsor here and they offer a price match as they stated in their post:

I didn't think Discount Tire sold the Continental ExtremeContact DW tires..!!?? I know they sell the DWS, but I'm needing the DW tire.

Any suggestions on the 235/245 fronts with 285 rears?

I'm running 255/285 on stock wheels. The oems are 225/255, so what would be the issue with 235/285? Should be fine.

I bought my Continental DW at a Discount Tire store, so yes they carry the DW line. When I bought mine, there was a national backorder of the 245s, but the AM at the store I bought them from, got them for me in a week (connections is a good thing).

When changing tire sizes, one should never go down in load carrying capacity. The 225/40/19 stock tire has a max capacity of 1433 lbs (load range 93Y) the 235/35/19s have a capacity of 1356 lbs (load range 91Y) and the 245/35/19 have load capacities exactly the same as the 225/40 tire. Also IMO, since the 235 tire is shorter than the 245 tire it will make the front wheel gap appear to be larger. And again, IMO, the OD is a bit to small.
