k, im going to use the stock steelies/tires as an example

tire size is 185/65/15

and i have on my car right now:

205/45/17

in comparison, the speed is 60.4mph : 60mph ------ 205/45/17 : 185/65/15
now, b/c there's a difference in speed, will this comparison add more mileage to my speedometer? or add less mileage to my speedometer?


another example is: if i were using 215/45/17 profile

the speed comparison will be:

59.6mph : 60mph ---- 215/45/17 : 185/65/15

in this case, my question would be the same, in this comparison, will it add more or less mileage to my speedometer?



as for my question about autocross/track.... im thinking of going with lighter rims.

is it wise to add performance/summer tires to 14 or 15 inch steelies? or would it be best if i go with performance light rims??

As for your first question, 205/45/17 will result in slightly MORE mileage on your speedometer. 215/45/17 will result in LESS mileage to your speedometer.

definitely go with performance light rims, either 14" or 15" is good, steeles might not be strong enough enough to handle autocross an it aint light, btw u going to bronte go station this sunday for covette club solo2?

it is not wise to go autoX or track with any steelie.....
steel rims do not have the structual integrity and steelies are heavy **** ******.....

your ideal size for track would be 15"x7" rims with 205 55 15 tires...

215 tire width will hamper your overall speed especially in the straights, but will give you better cornering stability because of a larger contact patch....but in order to run a 215, you will have to have a 15"x7.5" rim which doesn't exist....15"x7" will be a tad too small...

any reasons on why 16inch?

most ppl say 15in.

thanks.

go wif 15" light weight rim.... and get a set of ra1...
that way it'll be cheaper than 16" plus it's gonna be light..
civic is good on 15"

 
Rep Power: 0

my personal opinion... if you get light rims 16 is good too...I just like the look of 16's better than 15's ...15's on after market rims looks to small for me

 
Rep Power: 0

having 16" just because it looks better is not a good enough reason ...especially when we are talking about potential racing/lapping at the track....

its true that you can get light weight 16"....but a light weight 15" is even better...less unsprung weight and rotational weight = faster acceleration and enhanced throttle response.....now...if you wanted to say that you can get 16" as light as 15"...then $$$ might become a factor....but that's just the rim we are talking about....

how about the 16" tires? there aren't any lightweight tires....and 16" tires, especially RA1 aren't that cheap compared to 15".....the size you most likely be choosing if you went with 16" would be 205 50 16 or 205 45 16....

why 16" when you can run 15"? looks as a reason isn't strong enough to justify running 16"...

get victorracer for better grip, but not last as long as ra1 which is better on wet and last longer

you aren't fired alppy....

but honestly speaking, your comment about the 16" because they personally look better and that the 15" are too small just isn't valid enough reason to run 16" espeically at the track..

the topic of the thread or line of questions/comments/suggestions is autoX and tracking related.....aznsaint is most likely going to benefit from a suggestion that is more performance oriented than "it looks better" .....it looks better doesn't give performance....

so alppy....perhaps your comment about running 16" would have been more valid if you had said that the 16" would enhance performance because (and give reason)....

Alppy...i know you meant well about your comment...and trust me...you aren't fired....its just that the reason you gave wasn't strong enough.....

I'm running 15" rims now..and so is Ken....is it really that hard to look at?? does size really matter??? hahahhahaha...its always about the overall performance.....hahahha....

everything is cool alppy...dont worry .....

what would you guys think about me running at shannonville or auto cross events with honda stock rims?

the 2002 Si rims - 15 in

or

2002 seden special edition 15in rims... enkei edition

or

2000 sir rims??

with .... most likely falken tires....

or would it still be better off if i go with after market rims???


thanks

 
Rep Power: 0

well....it all depends on how much you want to spend....

As for myself, I am running my stock SiR rims with Toyo RA1. Then the other guy is running stock SiR rims with Yokohama A032R and the other one is Spoon SW388 with RA1.

The SiR rims aren't the lightest, but they are also not that heavy.

However, there is one thing to point out as I may have mentioned before. Most likely you will run 205s right? The stock Honda rims are 15"x6.5" and 205s, especially for track fit a lot better on 15"x7" rims. The sidewall is more square and thus allowing you to use more of your contact patch. But when I was running on track, it wasn't too bad. Hope this helps.

If you are interested, I can get your a nice set of A032R if they have the size you looking for.

SIRB16, just wondering, have u ever run your ra1 in reverse direction?i heard peformace is still the same on dry with reverse direction, but must run in correct direction on wet, and one more question, how much is 1lbs of unsprung equal to normal weight? and how long your ra1 lasted?

thanks

 
Rep Power: 0

thanks.. well, my budget is 1000, after selling or trading my motegi rims.

so that's why i may trade for stock honda rims... either the sir rims or enkei rims.. and get some falken tires.....

or get luck out and trade for some light weight performance rims.

on another note, i would still need these tires for everyday driving as well.

 
Rep Power: 0

are there any typical rims that come in 15" x 7" ????

as you said, the honda stock rims are 15in x 6.5in................

 
Rep Power: 0

i say for the budget and best performance, get the 6thgen sir rim + falken azenis or kumho mx, best tires for autox, will icq you soon, might know a place that can get the toyo t1s very cheap, but forgot where i put the ph#

or

if u can spend around 200 more, get new rota rims + tires, or get second hand if u can find it

 
Rep Power: 0

ya, im thinking about rotas... im trying to find 2nd hand.. but it's hard.

brand new is like 700 to 750 for 15inch.
and then plus tires.. that'll come out to abuot 1000 and over....

cheap toyo t1s...? hmmm, haha.. will these last me long though.. enough for all track/autox/ and everyday driving? haha

 
Rep Power: 0

the t1s should last you about 20000km if u are not really hardcore about going to track and autox

 
Rep Power: 0

macrossranma: i think the ratio is 1:10 for your unsprung weight question.

1lb of unsprung = 10lb of sprung

Majority of the people will run the RA1s to when there are only 4 lines showing and the side water evacuation lines are gone and then direction no longer matters. The performance doesn't matter between the directions at this point.

I just got my RA1s. But a friend of mine, I think he went through about 13-16 lapping days. It depends on your driving and other conditions.

i suggest Kumho 712 for best bang of the buck. although they are not the greatest tire for track or autoX but good enough for everyday driving and cna't beat the price and thread wear (320)

as for hardcore track and auto X ppl, get RA1 or A032R if u can afford it, they really worth it cuz i was in my friends' car with those tires and they kick *** in Shannonville

the Falken are relatively heavier tires than Kumho from my research and understanding

good luck with the selections
